If you can OC your system try it out and see if you get any increase in frames. Turn it up until the frames stop going up and stop there for efficiency.
I get 220-300(max capable) FPS in Counter Strike: Source on 1920x1080 8xAA All high.
Woops didn't have my Sig activated,
heres the rest of my Set up, Running 3 monitors in eyefinity soon, so 1920x1080 Resolution, Or 5760x1080 Resolution but not sure how much more processor it takes up with eyefinity active, I think the card takes most of the brunt.
My system does OC easily but takes a bit don't got a ton of time right now to be toying with it alot due with exams next week.
Just wanting to make sure that I'm not missing extra FPS when it is there for me.
