All I can vouch for is the 7950 does OC better than most from my experience and what I have seen, and I can hypothesize that AMD gives the user more freedom to OC than Nvidia. More freedom =/= better overclocks though, because it doesn't matter if the slider is locked if you can't hit that max limit! :doh:
Linus definitely seems like shill city (as if the Intel ad at the start of the video didn't give it away :shok. TBH, he didn't really even mention the 7950 beating it through the video, but just focused on Nvidia vs. Nvidia performance...
While I agree apples to apples is most truthful, a review like his makes for an interesting read/listen/watch when there are hundreds of apples to apples reviews!
And that i think we can all agree on.
