i need some advice on upgrading my GPU

[max sydow]

I am thinking to replace my GPU to 590 , my current GPU is 660 , when playing Call of duty black ops 2.0 my performance with Virtu MVP 2 is 130 FPS, does anyone with 590 can share what his FPS when playing with Virtu MVP 2.0? If you have same results with Diablo III, it would be great !
