Yes your problem is single GPU. 3dmark11 scales multiple GPU's extremely well. With another 570, overclocked, you would probably take number one spot or get very close.
Whats your CPU overclocked too? And what are the overclocks on your card?
With an I7 920 at 4ghz and a single gtx570 overclocked to 900 core clock I got like 6100.
