Gigabyte's CPU support list for their 2011 mobo GA-X79-UD7
is very short: Core i7-3930K and Core i7-3960X. (The CPU has to be a 3xxx series, so the 2700k is out.) Those are insanely expensive chips, but if you can afford them, go for it. The mobo ain't cheap, either. You'll need memory, too.
I'd get a cheap AMD mobo and ride it out.
