I just got done watching a video where the guy had two of the new Asus ROG Ares II cards and when he over clocked them he lost points in his benchmarks I am planing on dal 7970's with a i7-3930K be a bottle neck in my new system? I wouldn't think so but after watching that review I wanted to be sure.

Bottlenecks don't work that way. It was either faked, or there was something else going on. If it were a bottleneck, the benchmark would have stayed the same. (And, just so you know, an i5-3570k won't bottleneck a pair of 7970s.)
Considering most people here are gamers you're not going to get an absolute answer.
Yes an i5 will bottleneck 2 high end cards, no program that fully uses 2x high end cards 100% all of the time can run on an i5, for instance, Editing/rendering that uses 2-4 Cards can't use a single i5 or even i7 sometimes.
The only reason gamers can't see bottlenecks is because their cards are never used to a high enough level for the bottlenecks to show, hence people running i5 with 2-4 cards.
