I'm looking at scan.co.uk and not one of the X58 or P45 boards has SLI, is this a cock up with their information or is this part of Intel and Nvidias current tantrum? Ideally looking to find one with DDR3.
P45 boards will never have SLI capability.
Certain X58's can though. What chip do you have/plan on getting?
P45 and X58 are 2 different sockets, so you have to decide on a CPU first.
