I am in the process of building a racing simulator for my son and I will be repurposing a 6600k paired with a Radeon R 390. I'm not sure if we are going to use three older monitors I have laying around or try to find a better single curved monitor. If I wanted to upgrade the gpu, what should I be looking for? No 4k resolutions here. At best, three 1080 monitors or one 1440 ultrawide. I understand that most racing simulators for the pc are cpu intensive but I think the 6600k should work. Just curious if the gpu needed a bump in performance.
