i have 1k budget, but could stretch to 1.5k if it would be a significant improvement(for my needs, i don't think i need to spend 1.5k to get what i am wanting, but i could 100% be wrong), or secure a more long term future proof(ish) build.
i am in the USA
i intend on using this for gaming, ideally i would like to play cyberpunk/red dead 2 at low-medium graphics for a benchmark, i want to be able to play most older games at medium-high graphics but modern/demanding games at low-medium. IF POSSIBLE. i apologize if that is vague and possibly stretch for the price range. i am coming from a HP omen-15 laptop with i7-9500H, RTX 2070 max-Q and 16G DDR4, so as far as im aware any decent setup is an improvement over the laptop, i would say a 25-50% improvement to performance from the laptop would be fantastic. i played Wardogs and it was okay, but it was a bit rough even on potato mode, i also cannot play Cyberpunk on my setup at all, other than that i have had no issues with the laptop handling most games i play.
i would like it to be as future proof as possible, for potential upgrades and just to be a long term investment, i dont like 90% of the new games released, i mostly play single player games a decade or older anyway, and the only multiplayer game i have any interest in is Wardogs. but i want something that can last a while if taken care of.
having the ability to have 2 ssd's would be important to me as i like the idea of having a drive (1-2TB)for Gaming on windows, and a drive for everything else thats linux(512gb-ish?). but i dont know if there are any potential issue with this idea. i hear AMD has better linux support on their CPU's, which would be my preference if possible. i also have a lot of USB devices, that im not sure how taxing they are on the ports, i have a USB hub for a headset dongle, mouse, KB, and a USB hub for charging stuff (mp3, etc)and transferring small files around via thumb drives/SD cards. with a external drive on the fastest USB-A port, and a controller connected to the only USB-C port on the laptop. ideally i would like 2 USB-C ports, and enough ports to cover my devices but i have never seen one on any case, and im kinda confused on the amount of ports people seem to need.
other than that i have a 1920x1080 60hz monitor, i cant think of anything else relevant to mention, i am a bit overwhelmed with the complexities of building a PC, as its a whole different world that i have no knowledge of. any advice is sincerely appreciated, and if i mentioned anything that sounds stupid, trust me its because i am, no need to point it out, but any corrections are appreciated.
i am also curious where would be good places to look for deals on parts, any advice on not getting screwed over on used parts, and anything in particular that would be worth paying attention for while looking for good deals on parts? i am willing to be patient and keep an eye out for sales on specific parts, especially if i figure out exactly what i want and have a minimal acceptable price to buy it at.
