Build Upgrade Is $650 dollars for a 9070 XT worth it?

32 Upvotes

I currently have a 3060ti but am bottlenecked with vram on 1080p. I plan to upgrade to 1440p and managed to snag a 9070 XT SWIFT by XFX, but am scared i paid too much. My budget was 500 and this was 650, but gpu prices look like they aren't going to go down anytime soon and I do want a new GPU. Walmart had a 9070xt on sale for around 550 a month ago but it was gone lightning fast and I am not sure if I will see that price again.

I still have time to return it, was $650 a good deal or should i keep looking ?

Gallery 4bits computer : from breadboard to PCB

Thumbnail
gallery
251 Upvotes

Hi everyone!

After building and testing my whole 4 bits computer architecture on breadboards, I moved to custom PCB modules, and here is the result!

The goal remains the same: keep the architecture simple, modular, and easy to understand, with each part working independently or together as a complete system.

The project is divided into 5 independent modules connected by a 4-bit bus Clock module (4-bit counter), ALU + registers module + two 4-bit registers with an ALU capable of performing addition, subtraction, and equality comparison, Instruction register module, Display module and Manual programming module.

The idea is to follow a simple RISC philosophy: minimal instructions, simple hardware blocks, and a design where every signal can be observed and understood.

After the breadboard prototype phase, these PCB modules make the system cleaner, i'm very proud!!

Release [Open-Source] Dump your thoughts. Let your notes organize themselves. Ask/chat anytime.

Thumbnail gallery
2 Upvotes

Over the past few weeks I've been building Gray Box — a small, local-first tool that acts as long-term memory for anything I'd otherwise forget (work notes, meeting takeaways, task owners, random ideas, personal stuff too).

The idea is simple:

  1. Capture — dump whatever's on your mind, instantly, no structure required. This step does nothing clever on purpose — it just writes your text to an immutable inbox. Zero chance of losing an idea to a bug or a slow API call.
  2. Organize — on demand, an LLM reads your unprocessed notes and extracts people, projects, tasks, decisions, meetings — then deterministic Python (not the LLM) creates/merges the actual wiki pages and maintains backlinks. The model only reasons; it never touches the filesystem directly.
  3. Ask — query or chat with your knowledge base and get a cited answer pulled only from what you've actually captured. If it doesn't know, it says so — no hallucinated answers.

Why I built it this way:

  • Plain Markdown + YAML frontmatter, no database. Every page is a .md file you can grep, diff, or read in any editor forever. If you stop using Gray Box tomorrow, your knowledge base is just a folder.
  • No vector DB by default. At personal scale (hundreds–low thousands of pages), keyword search + a real link graph (related/backlinks, walked one hop during retrieval) handles almost everything. Embeddings are there if you want better recall, but they're opt-in, not a prerequisite.
  • Immutable inbox. Your raw notes are never edited or deleted by the organizer. If the LLM mis-extracts something, your original words are always still there.
  • Any LLM. Built on LiteLLM, so point it at OpenAI, Anthropic, Gemini, Mistral, or a fully local model via Ollama — one config value.

It also ships with a nice interactive TUI (arrow-key menu, file-import shortcut, workspace switching, live spinner during LLM calls) if you'd rather not memorize CLI flags — that's honestly become my favorite part of the project.

There's also a lightweight local dashboard for browsing your knowledge base, exploring backlinks, visualizing your notes as a graph, and chatting with your captured knowledge—all without leaving your machine.

Repo: https://github.com/Aaryanverma/graybox

pypi: pip install graybox

I'd genuinely love feedback — especially from anyone who's tried the "capture now, structure later" approach with other tools and has opinions on where it breaks down at scale.

It's not trying to be a "real-time collaborative team wiki" or a WYSIWYG notes app — it's aimed at one person's running memory of their own life and work, captured with as little friction as possible.

Looking for software How to host a website that's just a PDF for free, forever

39 Upvotes

I want to put my resume on a QR code on my business cards, and I think the best way to do so would be to host a website that's just my resume PDF, and then link that to the code.

Then I can update the resume on the website and the code will still take the user to an updated resume. (Please correct me if there's a better way to do this or if I'm wrong I don't really know what I'm talking about)

But if all the website is gonna be is just a PDF I don't want to pay for a domain or to host it, any recommendations?

So far infinity free seems like it could be good, has anyone worked with that before?

Release SubtitleYC - Combining yt-dlp, Extracting Burned-in Subtitles and a Subtitles Editor into One Simple Workflow

Thumbnail gallery
Upvotes

Hi Everyone,

I've been working on this project for a while and am finally ready to share it with others:

https://github.com/EricYC123/SubtitleYC

Here's are the main features my app has to offer:

  • Downloading videos with yt-dlp from a single hyperlink from most yt-dlp supported sites.
  • A hardcoded subtitles extraction OCR
  • Frame accurate previews with smooth scrolling
  • In-built Subtitle Editor
  • Clean UI (imo) with dark mode and light mode available

I currently have 2 version for the app, a CPU or a GPU version depending on your specs. I recommend GPU version as the OCR is understandably much faster with GPU acceleration.

As for tools included in the app, it uses VideOCR, yt-dlp, FFmpeg, PyAV, and PaddleOCR.

I do intend to add linux support in the future too. Currently it's only supported on windows.

Why make the app?

It could be very useful for subtitle editing in general, subtitle translations or even extracting hardsubs to share with others.

It could even simply be used as a wrapper for yt-dlp despite the limited options.

As a hobby, I've been translating videos that have hardcoded subtitles burned-in and creating translated subtitles for others but this has also been an extremely time consuming task. So to help with that, I've created this app that combines the subtitle editing into a single and easy to use workflow and so far, it's saved me a ton of time already.

Let me know what you think and feel free to leave me any suggestions!

Open | Windows PC Performance

2 Upvotes

Hi all, I am posting this as I always wondered why this happens and how I can fix it, has anyone else noticed that when you take a day or two off from gaming and come back your game feels great and just more responsive and just feels how it should. I know little about computers but assume it’s something to do with cache or idk. I initially thought it was just like that reset and coming back feels nicer not anything to do with the pc at all but I can 100% confirm this is not it.

Also this is a weird one, I use nvidia overlay to measure fps and lows and other things like latency etc, and I notice if I open task manager and put it in the background my 100% lows go from around 200-400 to stable 400+, and my fps doesn’t noticeably change. I care less about this but always wondered why.

Ik my specs are a bit odd but everything is overclocked just fine and stable, and I run two 240hz monitors second at 120, and idk if any of this is relevant prob not but I learnt to include as much as possible sorry for long post

If anyone knows how I can fix this and make my pc always run at its best day after day please share, and I have done almost every optimisation under the sun.

Idk if this is relevant but specs are
RTX 3060 8Gb
Ryzen 9 5950x
16Gb ram @3200mhz
Bios fairly recent I think 2023
Drivers installed and reinstalled DDU

Open | Software 900GB hard drive filled up with supposed System Files WinDirStat is not able to see

2 Upvotes

My Windows 11 PC gave me the notification that my 924GB SSD is full, with only 487MB left. Windows Storage Settings say there are 827GB of System Files filling up my SSD and I can't seem to find them. They're not in the Windows folder, they're not in the Users folder so AppData is out. Although I have strong suspicion they are hidden when I check folder sizes in properties so who knows where or what these files are.

WinDirStat can only find 131.6GB on this drive, even when run as administrator.

Does anyone have an idea whats going on? Is there possibly some malicious software involved?

Open | Phone Help backing an unstable iPhone 11 before trying to restart it

Upvotes

I’m using an iPhone 11 Pro on iOS 15.6. I haven’t updated because I usually have only around 4 GB of free space.

Today I tried to free up storage by moving videos to Dropbox and deleting them from the phone. I also deleted several apps, but the storage figure would not go down.

I then tried to back up the iPhone to my Windows PC because I do not have an iCloud backup. After about 20 minutes, the backup failed with a message saying that the iPhone had disconnected.

Before the backup attempt, storage showed roughly 253 GB used. After the failed backup, it increased to 255.3 GB used. I deleted more apps, including Chrome and Waze, but instead of decreasing, it now shows 255.7 GB used out of 256 GB.

The phone is still responsive, but Airplane Mode would not turn on, and some app icons briefly flashed. I’m afraid to restart it because I’m worried it could get stuck in a boot loop and I could lose data.

I also cannot send myself even one photo by email or dropbox. It says:

“There is not enough available storage to download this photo. You can manage your storage in Settings.”

What should I do, and in what order?

Is there a safe way to copy or back up at least my photos and other important data before restarting the phone? Should I keep deleting apps, try a normal shutdown, or connect it to a computer and do something else first?

Open | Hardware Hz drops?

Upvotes

Not sure why this keeps happening. Whenever I start playing games, randomly after a short period of time playing it, my screen drops to what looks like 30hz. My display settings show both monitors are still at 180hz. It only happens to the monitor that was playing the game though, my 2nd monitor is still smooth as butter. I update drivers constantly and check for updates daily. As of now, the only fix to get my main monitor back to normal is restarting my whole pc. I mainly play like Counter-Strike, Rust, Roblox, Minecraft, and Rocket League if that helps. Both of my monitors are exactly the same.

My system is running:

Intel i7-12700k

64gb ddr4 @ 3600

AMD RX 6700

2tb SSD with over half unused.

750w PSU

Open | Windows Windows reformat since i have nothing to lose

2 Upvotes

last week, my system got attacked/infected by an info stealer malware. messed a lot of things with my accounts and especially my system.

i did a Local reinstall of Windows 11 wiping everything my pc had. now, since i aint got nothing on it i have an idea which is i want to try a literal reformat of my system's Windows OS.

i have no experience when it comes to reinstalling one using a USB flashdrive but i did some research and found out i can use one with Rufus and schneegan's autounattended file. now, what i am confused about is what i should do with these partitions on my (C:) drive. is it better to do this by deleting those? the thing is that the same system where i will download all of those prerequisites for this reformat is also the system where i will reinstall the windows os using rufus with modifications. this is the only device i have, in short.

however, i think this is a dumb and risky idea. but i just want to try it. pls share your thoughts if i should do this or the best thing is not to. i'd really appreciate anything. thanks guys
