Good lord, you have no idea what you're talking about and these poor people modded you informative?

First, you can get a loaded 965 board for like $150. Second, Conroe at stock speeds only needs DDRII-533. DDR-II 667 would allow you to use a 1:1 ratio and overclock an E6600 to 3GHz. You don't need DDRII-800, that's just uninformed nonsense. In fact, you're 180 degrees wrong - Conroe can use cheap memory, AM2 needs expensive memory.
