Marduk is from my Team.
He is not a cheater. Its just a problem where hes using SLI (actually, his score is low for SLI), and probably the bot recognized it as single.
I also have a problem there with X1900XT CF, and also my X1950 Pro is not recognized.
Even that, Were not cheating. There is just one score which was submitted and It was reported as cheat. I checked it and erased it after talking with the guy which sumbitted it. So, there is no problem anymore.
