HI i just upgraded form a zotac geforce 640gt to a zotac gtx 760 AMP i feel the change right a way, much smoother frams but when i look at my fps i am get just 60 max 68 and have some dips to 48 fps but i dont feel it i am running it on all low setting. what with the low frams on low? the rest of my computer consist of 8GB of ram, AMD phenom II X4 960T cpu, zotac gtx 760 AMP, Win8 pro and 550w PSU.. oh and yes i have the latest driver for the card!
