Bribed? Probably not.
Using the wrong hardware? Yes. Notice how they used a NVIDIA Intel Edition chipset. If you haven't noticed, NVIDIA has always been predominately Pro-AMD in almost all their chipset logic. Heck, the only reason why an Intel Edition chipset was even made is for the market's sake and to shut up all those Intel fans.
It's crap if you ask me, and see what would happen if you use a Intel 975X or P965 chipset.
By the way, that showdown thing is old. Also, you might want to be open minded with CNET and some of those tech sites, as they are biased towards certain products or brands.
