Which MOBO to pick??!?!

Whatever you do, don't get a nvidia chipset. You're better off with the Maximus II Formula or the Rampage. IF you're going to stick with 1 gpu, then go with the Maximus II (P45). For 2 or more gpus, go with the Rampage Formula (X48).

^+1 ...I got a Rampage.. - best board ever. I friend of mine got the maximus II... he mentioned that it is pretty sensitive when tweaking.

i think he should go with the nvidia chipset if he is goin to stick with the 260 cos in those chipsets only he can get a proper sli ...

I doubt I go SLI, if I ever did multiple cards, I'd prolly go with 2 4870's. What is wrong with nvidia chipsets?
