NOPE!
Mines better

they have a Q9550 @ 2.83Ghz
mine is Q9650 @ 3.00Ghz (not counting overclock, but I bet mines better too as you just cant get 4Ghz on a 780 with Q9550)
I have 8GB of DDR3@1600, they use DDR2@1066
They use either 1 GTX280 or 1 4870, I have 2 4870x2s

:D PWMT
They have 1 small and 1 medium hard drive
I have 2 RAID arrays

(Velociraptor RAID0 and Caviar Black Raid1)
They use Air, I use water
Thier screen is nicer IF theyr using the 30" but mine is dual screen so thats up to opinion (not the dual 20" as I have 26"+22")
Case is also opinion, but performance wise, Mine is better at airflow/build quality
And XP is dated now.. Vista and DX10.1 FTW!
