I have a very expensive pretty new computer, (Asus rampage III Extreme) (Intel i7 980x) and 2 (nvidia gforce 580 SLI).
So it is a good computer, but when I play games like Borderlands 2 I get much lower FPS than I am suppose to have, like around 30 FPS. And about 150 FPS when I am looking at the ground. The lowest FPS is when I look into like cities and that kind of stuff.
I checked my CPU and GPU usage and noticed that they both only used about 20-40% of their maximum usage. So I think that something is wrong with the CPU.
I have tried reinstalling windows, overclocking and some other BIOS settings. Not funny to pay a lot for a new computer and not be able to play even the games I could play on my last computer.
