I feel like an idiot about this but I didn't even know it existed. Guess I haven't been paying attention like I should to the operating system news...or AMD rather cuz I've always been intel. Well just got my MSI K8N NEO2 and it's got a free copy of WindowsXP 64bit (beta) Naturally I'm intrigued. Can anyone tell me if it's worth it over Xp Pro? thanks for the help
