Hi all!
I had following spec:
AMD Phenom II X4
GA-990FXA-UD3(rev 3.0)
Corsair Vengeance 8 GB ( 2 x 4 GB )
Sapphire Radeon Vapor-X HD 7770 GHZ OC 1 GB
ADATA XPG SX900 128 GB SATA III
Corsair Builder Series CX 500 Watt

Performance was decent, experience in games was smooth gaming with sufficient fps almost in any game. Then I decided to upgrade my graphics card to ASUS GeForce® GTX 650 Ti Boost DirectCU II 2Gb OC to get even better, and after it I got worse performance, namely I have stuttering in games(Bioshock Infinite, Far cry 3, etc)and picture quality also worsened(flickering textures and shadows on objects drawing as I move) although I got more fps in games. Tried different driver version(currently 314.22) but in vain.Very very disappointing, thinking to switch to amd's card like 7850.
Would be very grateful if any suggests possible cause. Thanks

Sounds more like a defective card. You should try returning it for an exchange. My first 6950 was defective, random green dots...sent it back, next one was fine. PITA, but sometimes Shi...Stuff happens. Only thing I can think of, did you properly remove all of the AMD driver before installing the NVidia driver?

Thanks for the answers. I've already checked on several drivers all the same. Yes before installing card deleted all amd drivers, except motherboard chipset driver which happens to be AMD. I don't think its defective but going to verify this soon as well by installing it on i5 processor with Intel motherboard.

Good idea. I assumed that since the Phenom worked fine to whatever settings you were used to, the 650Ti Boost should have worked at least as well. The CPU should not be a variable unless you tried higher settings on your games, in which case, of course the CPU could become the bottleneck, but if it still has the same exact problems on the faster i5 then you can be fairly sure the card is bad. Just make sure the game settings are the same as you had originally on the 7770 when you make your comparison, otherwise you are just proving you need a faster CPU!
