I'm going to stay with XP as well but I certainly gave Windows 7 (both x86 & x64) from the beta build to build 7100. Windows 7 x86 version installs fairly quickly and does find all the drivers related to the motherboard. All other drivers had to be installed by me. Some builds would bsod upon installing drivers. Some drivers designated for Windows 7 didn't even work - had to use Vista drivers. Windows 7 x64 version installs very quickly and again finds all the drivers related to the motherboard. I had a few issues trying to install my other drivers and again had to resort to Vista drivers. I personally found it ran slower than x86 version - it shouldn't because my computer is Vista Ultimate ready. I stopped testing the x64 version when I couldn't install certain software (mainly plug-ins for FF). The most important reason, for me, not to use Windows 7 is the new audio engine - well, not new for Windows 7 but should have been fixed. As a person who remixes and creates music, this is unacceptable. I work very hard to make sure no noise is introduced into the sound and here Microsoft is throwing it in for free. Here is an interesting article going into much more detail about Windows Vista (but still in 7) audio engine. If you get the same quality sound like you did in XP then I congratulate you.
