what upgrade would benefit my system the most , it is used mainly for gaming with a little benchmarking and web browsing .
specs below :
phemom II 955 @ stock
Gigabyte MA790X-UD3P
Kingston hyperX1066 2x2gb
2x Sapphire HD5770 cf-X
CM Silent Pro M1000W
Deskstar 7K1000.C 1TB x2
barracuda 500gb
Coolermaster cm690
acer V243HLBMD (1920x1080)
windows 7 x64
in farcry2 if i add any AA i get a lot of stutter although the fps is well over 70fps most of the time , in all the stalker based games i get stutter and it pauses for a few seconds in any settings apart from static lighting.
i think i would like a single gfx card but would say getting a 5850/5870 or even a gtx470 help ? , what upgrade would help the most to play these games with a smooth feel while gaming .
also sc2 dips to 19 fps in heavy combat/lots of units on screen , this upgrade would need to last me around 2 years .
advice welcome please
