K, I had my mind set on AMD 4400+ and 2 GB OCZ PLatinum and Asus A8N - SLI Mobo, but now I see that AM2 came out, and it's different socket and u need different Ram as well. So I'm confused right now. This will b my first custom build and I don't know much about specs to find out if it's really worth to step up to AM2 setup ??? Should I just stick with what i wanted to build from beggining or should I upgrade to AM2, also what CPUs r good from AM2 in no more than $600 price range ?
