Hey guys, I have an Acer Aspire 5100 that came preloaded with Windows Vista, and right from the start it was way too slow and laggy for me. Even though it has 1gig of RAM, some of that is taken by the Graphics card which doesnt make things any better. So, i decided i want to put XP on it because i am POSITIVE it will run alot better. But my only concern is... My laptop Processor is an "AMD 64 Athlon X2" I'm pretty sure this means i have a 64-bit processor. Now does THAT mean that i need the 64-bit edition of windows xp? or can i just any old regular 32-bit Windows XP Professional? And finally, can i be sure that all the drivers will be running smoothly and stuff after i downgrade my OS? Thanks in advance to anyone that can help. really appreciate it.
