Hello, I'm intending to upgrade an old PC in a few days. The IGP isn't that great for gaming. I've done some research and it's not so clear. Some say it'll bottleneck a 4670, others mention that a 4850 would run fine. Does anyone have any experience with this CPU? It's currently @ 2.3GHz and it probably won't OC any higher on my crappy motherboard. My monitor resolution is 1680x1050. The question is: Will a Radeon 4850 show any noticeable difference over a 4670 in this configuration?
