When I assembled my new PC I put windows 8 64-bit on it. I love it! It took some getting used to, as for the start menu was gone and the new search method is actually quite handy once you get used to it. All in all I love it. The only sad thing about is that Homeworld 2 is not compatible with windows 8, and I love that game. :( small tidbit: I've experienced no crashes, BSOD, or major problems with windows 8. Fyi.
