I have an Asus P8P67-LE, and recently discovered that I have a bad PCIEx16 slot. My other slot works fine, but I'm pretty sure that it will only run at x4. How much will this hurt gaming performance? It seems to run Crysis 1 just fine. I don't have a lot of graphically demanding games right now, but I probably will in the future. Basically, will I need to replace my motherboard if I want to run anything newer? I'm using a Radeon 4850x2 for my graphics.
