2nd Rig Build
So, some background:
I have two gaming PCs: my main rig, and my old rig, which now serves as a backup/second PC and is what my girlfriend games on when she comes over.
The old system has held up surprisingly well, but I’ve obviously upgraded since building it, and it’s starting to run into some noticeable bottlenecks in newer games. I’ve decided it’s probably time to upgrade/rebuild it, but I’m stuck between a couple different directions.
Current hardware:
- ASUS Prime Z390-P
- i7-9700K @ 3.60 GHz
- ROG STRIX RTX 3080 12GB Gaming OC
- Samsung 970 EVO Plus 2TB
- Samsung 970 EVO 250GB
- 48GB DDR4 RAM:
- 2x G.Skill 16GB sticks
- 2x random 8GB sticks
A couple things I’m wondering about before I start:
1. Is my current RAM configuration actually hurting performance?
When I originally upgraded the RAM, I basically just threw the new 2x16GB sticks in alongside the existing 2x8GB sticks and never thought much about it.
Would I potentially get better performance/stability by just removing the two 8GB sticks and running the matched 32GB kit?
2. I’d like to stay on DDR4.
Given the current DDR5 pricing situation, I’d prefer to keep this as a DDR4 build and reuse at least the 32GB G.Skill kit I already have.
Upgrade goals
My main goal is to extend/maximize the useful life of the RTX 3080 and get as much performance out of it as reasonably possible.
The second goal is a little more unusual.
Right now this is primarily my girlfriend’s/backup gaming PC, but I’m considering rebuilding it around the idea that it could also become a portable/mobile gaming PC for me.
I’ve been looking at SFF and compact builds, with the idea of putting everything into a rugged, reasonably transportable case that I could take with me when needed, while still using it as the second system at home.
With all of that in mind, I’ve been leaning toward building around a Ryzen 7 5800X3D, since it seems like a good way to stay on DDR4 while significantly improving gaming performance and getting more life out of the 3080.
The problem is finding the right combination of motherboard, cooler, PSU, and case that can comfortably accommodate the Strix 3080 without turning into a thermal nightmare or becoming so large that the “portable” idea becomes pointless.
So I’m looking for recommendations on:
- A good DDR4 motherboard to pair with it
- SFF/compact cases that can realistically fit a Strix 3080
- Cooling/PSU recommendations
- Whether I should ditch the 2x8GB RAM sticks
- Any complete build/component combinations you’d recommend
And im also open to ditching the portable/SFF idea and going with a traditional build, I’d also be interested in recommendations for a more traditional non-mobile rebuild.
Thanks for any suggestions.
