DubbleClick :
My own one is a z97x-sli, picked it up for $100 locally. A friend however bought the ud5h-bk (was stuck on the black design) and I have done some testing and benchmarking with my own i7 on it. The only difference I was able to tell was the mentioned 5.0ghz vs 4.9ghz of which both are beyond any reasonable voltage or temperature anyway though.
Well from everything so far I guess these would be my choices.
