Not including Crysis doesn't make this review irrelevant. Not including Crysis or CoD4, BioShock, Quake Wars, UT3, WiC, CoH, FSX, Test Drive Unlimited, Grid, Mass Effect, etc. is what makes this review irrelevant.
I don't want to sound mean, but you might as well have benchmarked Pong, Space Invaders and Pac-Man.
Flexing muscles of a $3600 rig against the games that a $600 rig can run at 60 fps is not very useful.
"The reason we didn't bench it is that the closest system we had to compare the iBuypower to was the Uberclock system, which Crysis wasn't benched on and we no longer have in the lab."
So what if you don't have Crysis benchmarked on any previous system? Why not start now? What is to prevent you from making the same excuse every time you review a machine? If you never take the first set and review the game for the first time, you will never have anything to compare the future machines to.
And I believe that you should run any high end system against the one you guys created few months back in your System Builder Marathon. That rig and those benchmarks should be your staples against which these machines should compete against.
Also, I think it would be relevent to include a mid-cost system as well, just to see what double the price will get you.
