So, i'm planning on building a new pc.

Only part i don't really now what to choose is the motherboard.

Gimme more info about it or tell me some good one's to choose from that are not overprised and a good bang for the buck.

Also, what's the main difference between socket 1155 and 1156 and 1366 in terms of performance and other necessary knowledge.
(Yeah, i'm aiming on Intel)
