I have used XP 32bit for the past 4 years and it has ran flawlessly. I recently purchased a new gaming computer from AVA Direct and had Vista 64bit installed and I have had so many issues that it's really starting to pull me down. Does XP 64bit have the same issues as Vista 64bit? Is the 64bit the problem and not the OS itself? How does Vista 32Bit compare in problems to the 64Bit version? Concerning Ram, I have 4GB and Vista 64Bit sees it all, but I hear that XP 32Bit will not. What about XP64bit and Vista 32bit?
