The reasoning should simply be, that the gtx 680 is a NEW piece of technology, and it should be coupled with recent other hardware as well. So yes, you should use an SB with it, because people who upgrade, will most likely use that CPU with it as well. It's just capturing the majority of your audience, really simple, rather common sense logic. Now, why no response from the author on 2 of the major flaws of this review? Oo No 580/570 SLI or 6970/7970 Xfire, and older HW!
