Re: ATI + nVidia PhsyX + Vista???
wouldn't know, i was always perfectly content with using pirate versions anyway, it was sort of fun to dodge around MS's little things to try and catch you out, like when they check validation whenever you install anything else 'Microsoft' and there stupid WGATRAY watermark would appear. I got my genuine copy for free from MSDN too, so i've still never actually bought an OS.
