A 9900 vs 6600? 
Not even the same price range or mhz.
They're not even comparing the same cards on different systems for any type of comparison.
Did anyone notice the Mushkin@1066 vs Kingston@677 difference as well?
They're the same latency, but a bit of difference.

Whenever they can actually place a couple PC's against each other at the same price range, I'll be a bit more impressed.
