So I downloaded it, did a clean install, and boot up with it ready to feel the blazing speed and awesome power of 64 whole bits of word size......................or not Turns out my mobo, which ironically supports only 64 bit chips, came with drivers that were written with a dos installer. IE they wont work with x64. So after about 5 hours of jacking with it.....I am back to 32 bit splendor with plenty of driver support. For those of you that are running xp pro x64 is it giving you trouble? Is the performance noticable say for instance when you are rendering video. I am about to give the 64 bit gentoo a shot (if I don't get any hardware support then I might as well try an os that is worth a shit). Anyone have an AMD 64 based system and had luck with a 64 bit os yet?
