evga boards in general have better quality power regulation components, and the warranty says it all. Not only do they allow for overclocking, a lot of their parts are built for it.
There is a big difference between an entry level $120 four phase PWM board, and a $200+ eight phase enthusiast board. If you're overclocking on a higher order than just pushing your bus up a few mhz, you don't want your vcore to droop, and you want your vdimm stable 24/7. To do that, you don't want to skimp on the motherboard at all, that means spending close to $200 on just the board, and that means no crap components allowed.
