Hello- I plan to build a 2nd comp for home. I want to do this really budget, but I want it to be ready for 64bit windows. What is the lowest cost processor family/socket I can build this around? Also, for a very basic mb to go with that processor,what would be good? It would be fine for this 2nd computer to have just onboard video and sound to keep the cost down. I plan to get 3-4 years of use from this, and I figure win64bit will be out by then.
