Windows 7 is a great operating system, especailly if you have a Quad core system 64 bit. and want to run more than 4 gig of ram. Vista is a memory hog. big time and had a lot of issues with 3rd party drivers. It takes just about 2 gig of memory to run Vista operating system .Cold boot time takes for ever. With Windows 7 , my computer boots in 60 seconds or less, my Vista machines take forever.
Run Windows 7 in capatibilty mode and I think you'll find your issues well be solved . Down load the latest Direct X driver . http://www.microsoft.com/games/en-US...s/directx.aspx also.
I build gaming computers and had all kinds of issues with Vista and older games. Windows 7 is so much better and I have'nt run into an issue that could not be fixed fairly easy. I also compete in Overclocking. and when I went from XP Pro to W7 64 bit my computer gained a 1/3 more speed . I also run 2 grafics cards in SLI and 7 really brought out this feature on my computer.
XP is a good operating system, but Microsoft is nolonger doing updates for it .
