Had all sorts of weird problems with vista 64, seemed OK at first sp1 has made it much better stuck with it for 2 months. I noticed when you try to install something there is a weird long delay before anything happens and games were not very stable, namely world at war took all sorts of tweaks and hassle just to get working multilayer online. After much tweaking and optimization it was still
having the odd random freeze.
Went back to windows xp x64 it was like a breath of fresh air, so fast and stable started gaming with world at war no problems higher frame rates and more responsive looking back I have to admit there is absolutely no benefit in using vista 64 at all, loss of stability and performance for what? direct x 10 ? a new search function and a pointless face lift that merely causes more problems and incompatibility.
Windows xp x64 IS the way to go for gaming, just tried empire world at war, it's also faster and more stable than vista in the real world. Seems to be allot of vista fan boys full of shit around the net it's slower and still has massive problems I had hoped it had come good my advice is go with what appears to be Microsoft best kept secret windows xp x64
