I agree go with the amd64, but make sure that if you do. go with the socket 939. The product that you linked us to. Wont allow for much or any upgrading at all. i currently have an amd64 3500+ s939 with the asus a8v deluxe. I couldnt be more happyi currently have it overclocked to better the 3800+ speeds with no problems whatsoever. but yes do let us know what ur budget is. and what parts you need. cpu, mobo, ram will cost between 400 - 700 dollars us. depending on quality or size etc.
