2 Ninja's, unless the mobo is made from adamantium, two ninja's will probably snap that thing in half... or how about 2 Titan Amanda's...
Yeah, the Kentsfield OC's very nicely, but it would push off a ton of heat... 150W I suppose? That will challenge even some water-cooling set-ups out there.
By the time second get 4x4 gets around, then native quad-cores should be out by Intel, and maybe AMD, so then we can see an apple to apple comparison. I'll leave 4x4 as a 2 quad-core solution for enthusiasts, which I probably won't talk because of the prohibitive price...
Wonder if Intel will make any dual 775 socket mobo's...
