Re: Windows 7 and Gaming :)
It depends on individuals. For me, I hated it. I used to have so much troubles when I had two 7800 GTX 512mb cards. Maybe it's because SLI was still pretty new. Or poor support from drivers. Either way, I rather deal with one card and run everything with ease. I have other things to worry about like my life and school.
