My CPU is i5-3570 and monitor 1080p. With HD 7770, I run Skyrim with max settings and fps is 60, so what improvements will I see with a 7970?
You dont run Skyrim at Max(Ultra) settings at a resolution of 1080p and get 60 fps with a 7770. Sorry, you just dont. Heck even toms doesnt....
a 7970 will max the game out with all the eye candy turned up to max. As for FPS expect 90+ or in that neighborhood.
