I wasn't arguing or complaining; I had searched for x64 drivers before I installed XPx64. I wanted to try XPx64 to run some benchmarks with XPx86, XPx64, Win7x32rc1, and Win7x64rc1 on the same machine. That way I could determine which OS actually performed better. I never tried Win7x86, but I still have that machine triple-booting the OSes, but now I primarily use Win7Ultimatex64 on it. By the way XPpx86 scored a few points higher than the others in 3DMark06 and Everest Ultimate. I was surprised because that machine has 4GB of DDR3 RAM and I knew XPx86 was only seeing and using 2048 of it. After some more research I concluded that the x64's use of WOW for 32-bit application was the reason they were a little slower - the OS was performing some extra operations to use the 32-bit apps. Since I was over 20,000 points in 3DMark06 anyway, I didn't mind, and Win7 added DirectX11 for games. My GPUs are 10.1 (HD 4870s), but I'll upgrade to an HD 5870 when I feel the need.
