I just recently upgraded from a 22" monitor (1680x1050) to a 24" monitor (1920x1080)
After noticing that the resolution took a bit of a performance hit i decided to get the GTX 660 2GB, upgrading from the GTX 460 1GB
Right off the bat i uninstall previous display drivers, DC pro and then install the new drivers.
I launch a few games, every game once it finishes loading a map or campaign mode my computer would restart, no bluescreen nothing.
I figured right away it's the power supply as it is a 500W power supply, not the best quality brand either.
I install a 650W corsair power supply and all my games work, i notice my hard drive getting very noisy, almost to the point where it began to worry me of its lifespan as i have had it for a few years (WD cavier black)
I reformat my pc and install Starcraft 2, Crysis 2, CS:GO and Max Payne 3.
Upon running these games, there seems to be quite a tiny bit of stutter, its not as fluent or smooth as it should be, i mean it looks smooth but it still feels like its holding back. I guess this time i am assuming its my hard drive that can't perform well anymore, or could it be that i have a bad GTX 660? i get about 40-50fps on Starcraft 2 in extreme settings. also on CS:GO i get about 90-150fps but even with such high fps there is always a corner or so that makes me stutter a tiny bit.
Crysis 2 i get about 30-40fps on ultra
Or could it be the fact that my motherboard does not support PCI-E 3.0? is there any performace difference between PCI-E 2.0 16x and 3.0?
CPU: Phenom II x4 965 3.4ghz (@3.6ghz OC)
GPU: GTX 660 2GB
Motherboard: Gigabyte GA-MA770-UD3
PSU: Corsair 650W
Soundcard: Soundblaster X-Fi Fatal1ty pro
Hard Drive: WD Caviar Black 7200RPM 1TB
Edit: The reason i reformated my hard drive was because my performance was either the same or worse, and my hard drive was so noisy and my desktop running too slow i figured it needed a clean up, hard drive is a bit more quiet now but noisy when i load anything.
