Seconding @theunknownmuncher@lemmy.world, don’t accidentally sleep on AMD GPUs - they offer better performance dollar-vs.-dollar than Nvidia; are much better supported in Linux (if you ever get sick of Windows 11), and you also wouldn’t be rewarding the biggest architect of the current PC component pricing crisis!
In terms of what to check for, compatibility wise:
- GPU dimensions (new card isn’t longer/wider/thicker than your current system can support)
- Power requirements; ensure your existing PSU has enough of the right connectors (6/8 pins), and that it meets the new GPUs recommendation
Either way, happy gaming!
