I want to thank all of you for all of the great advice you have given me. At first I was trying to reply to each email as they came in, but then I went out for a bit and came back to over 200 emails, and decided to just read them. So thanks to everyone who wrote in to help me out.
I have decided to stay away from the Athlon64 for now, and will build myself a nice XP system.
I also am going with either Corsair or GeILM RAM.
Thanks everyone. I’ll let you know when I make my final decision.
