i guess this is a good time to point out that the socket 775 uses less pins than the socket 939 ... lol
im sorry. i just thought of it, being that intel is using less pins....
anyways... to the point about changing the motherboard with conroe... you may have to, depending on the fsb limitation(?) in the bios. but then again... im not an uber leet computer geek that stays updated on the technews channel.
