I’m currently using an AMD 5950x and an Nvidia GeForce RTX 3080 LHR, pushing video to a Dell U4021QW, which is a 40" monitor running 5120x2160@60hz. A few of the games I play are pretty challenged at that resolution, so I’m thinking of upgrading at least the video card. Is there any reason to build a new system with a newer CPU as well?
Look at your bottlenecks for your applications, are you CPU bound? If not then don’t upgrade the CPU
In case anyone is wondering how, MangoHud is great for monitoring system performance while gaming on Linux.
