the 2011 is the cream of the crop in terms of bandwidth and performance, but the real question is dya have teh extra cash to drop all of that onto your other hardwares?
reason I asked is cos most people yearn for a ferrari but later say they don't have the money to pay for the fuel to drive that thing.
I'd suggest getting a Z77 mobo for half the price you'll be shelling out on.
my rig would be something like this:
MSI Z77 Mpower
8GB DDR3 1600/1866 Ram
at least 1x256GB
GTX 680 or maybe a 7970
cases - well that will change depending upon your taste.
but ifs its board advice you want - Z77 all the way.
my 2 cents
