I am in the process of building a new computer and want to get the best price/performance ratio out of it since I don't have a lot of cash. Therefore, I want to go with AMD so I can hopefully overclock. The buyer's guide on this forum said that the Barton processors are not very cost efficient. What would be my best bet then? I take it the Athlon 64s are going to be the best bet long-term but they're pretty expensive right now. I currently have an AMD Athlon XP 1900+. Should I wait around for prices to drop more and keep using my 1900 or go for something like a 2500 or even dish out the extra cash for a 64? Also, what sort of motherboard should I get with the processor? Any thoughts are much appreciated. Thank you.
