Hey, I just bought a P4 Socket 478 3.2E Ghz CPU. 800mhz bus, 1mb cache...etc.. Anyways I was just wondering, did I make a mistake? Should I have gone with Socket 775? And what is the difference between socket 478 and 775? I have only bought the PCU for my new system, so I am at the point where I could probably return it and get something else. Any advice would be great...thanks!
