It's incredible how much slower the 7800GTX is than the 7900GT! My CPU is alot slower than his, and I score 500 more 3DMarks higher than WWS.
And before everybody flips out, CPU DOES make a difference in 3DM06! Even at stock 7900GT speeds, I score more than him, and I'm running my 4400+ at its measly stock speed too.
