Unfortunately I had to go to Vista, since I could not get my two 8800GTX working in SLI under XP with the newest Nvidia drivers. I could get SLI working with a very old driver but that gave other problems, obviously. Now with a a Vista install, my SLI works just fine. I probably still could get better framerates with a single 8800 GTX in Windows XP, but let's not go there. :D At least I am ready for the "future".
