zack1234,
if you are able to, switching over to Windows 7 64 bit might be more stable OS for you than your current Vista OS ( Windows 7 is also a lesser resource Hog than Vista I do believe )
also, your Acer System sounds like it is all AMD ( your CPU is AMD< you had an ATI video card, and probably the Northbridge and Southbridge on the MotherBoard is AMD as well )
for a Nvidia VideoCard to perform "Better", your AMD Socket MotherBoard would be better off with Nforce(Nvidia) North and South Bridge chipsets.......... verses using a Nvidia VideoCard on an AMD platform with AMD chipsets..... it might work, but it might also cause you headaches
if you want to invest in a New ATI card..... I would suggest getting a 6850, 6870, 6950, 6970 model preferrably the 6870 or 6970 model
I opted for the XFX 6870 recently instead of the XFX 6970 only because the 6870 model offered 2 cooling fans verses the 1 cooling fan on the current 6970 models from XFX ( the 6870 XFX model also originally came out with a 1 fan design, but they upgraded it on the Black Edition and another similar 6870..it is like the Black Edition model but is not overclocked from factory )
anyhow........ make sure when using that driver cleaner, that you only remove the AMD/ATI video,video sound, HDMI, CCC, etc drivers...... removing any of the MotherBoards other AMD drivers will cause you other major problems maybe.......
hope this helps....... Best of Luck
TC
