I have an old PC I use when visiting family and right now it's running Windows 11, but I've had to bypass some TPM requirements just to make it work. I'm thinking of switching to Linux for my main setup, but want to test it out first on this older machine to see if it can help with performance. nnThis PC is mainly used for light gaming, email, and web browsing. Here are the specs: nn- Intel Ivy Bridge 3570K (with a small overclock) n- 32GB DDR3 RAM n- 2 x 500GB 2.5" SSDs n- Nvidia RTX 660 Ti (overclocked slightly) nnI just upgraded my main PC's GPU, and I'm considering swapping that with an AMD RX 6600 instead of selling it if it would run better on Linux. I mostly play indie single-player games and some multiplayer games online (nothing that uses anti-cheat software). nnI'm looking for recommendations on a gaming-optimized distro. I was considering CachyOS for my main PC—would that work well on this older setup? PikaOS is also on my radar, but it doesn't support CPUs older than Haswell, so that's out for this PC. Any insights would be appreciated!

Don't overthink it! Any mainstream distro will run well on your setup. I like OpenSUSE and Fedora, but you can't go wrong with Ubuntu either. Just pick one and give it a go; you can always switch later if you want to explore more options.
Your 3570K should handle any lightweight distro just fine. A good desktop environment makes a difference, though. Go for something like Ubuntu or Fedora to start—they're both user-friendly and should work well without taxing your system too much. Plus, you can test them in a live environment before committing!
CachyOS might not be the best fit since it doesn’t optimize for 3rd gen Intel processors, plus your current GPU could face support issues with the latest kernels. You might find better performance with a more stable distribution aimed at newcomers, like ZorinOS or Pop!_OS, which usually come with the necessary drivers pre-installed.
Totally agree, sticking with a more user-friendly distro will make your life easier, especially if you're new to Linux!
Thanks for the tip! I'll definitely check those out.
If you plan to switch to an AMD graphics card, I'd suggest starting with Linux Mint 22.2 with the Cinnamon desktop. It’s known for stability, and you’re less likely to face issues during updates, unlike with certain Arch-based distros.
Honestly, most current distros should work just fine with your hardware. The main limitation is your GPU. If you're using a 660 Ti, you're gonna hit some bumps with software that employs newer drivers. An older driver version might not perform well, so switching to an AMD card like the RX 480 or 580 could save you a lot of headaches.

Thanks for the reassurance! I'm excited to dive in and try a few.
