I have a quick question about how CPU and mobo's go together. I'm completely new to all of this, and everyone here seems really helpful. As I have described in other threads i'm having trouble finding a motherboard for my Intel Celeron 2.50GHz 845GV CPU. The Socket number is 478. Does my CPU just have to match the 478 socket, or is it deeper than that? Any info on this would be great.. and if someone could explain how all of this works, it would be even greater. It's driving me crazy. :rolleyes: If you want to help me even more... here is another thread of mine. http://www.techspot.com/vb/topic21629.html Thanks!
