I have an XFX Radeon HD 6770 1GB GDDR5, and my processor is an Athon II x4 650 3.2GHz. I play a lot of my games on max, but some games (DayZ [ARMA2], PlanetSide 2, GW2 to some extent) I have to play on low settings for them to be playable to my standards (40+ fps, constant). Is it my processor that is holding me back on these games, or is it the GPU? Thanks!
EDIT: I already plan on upgrading to a Phenom II x4 965, but will it be a noticable difference?
