ok well when i moved my parts from my old pc to my new pc case i geuss i burned my cpu ( dunno thats what my uncles said and hes a wiz wit computers) so now im going to build a new pc. Im kinda on a budget right now and he already ordered my new parts with out telling me and i looked over them and i didnt want most of the stuff he got me so im just going to return it but i was wondering whats the difference from a 650i mobo and a 680i mobo, since im looking for a new sli motherboard.
