Tbh I have yet to ever be happy with 3dmark runs on every rig I have built no matter how much it cost me. Thought id destroy it when I spent 1400 (NZD) on 2 5870s at the start of the year but no got a fairly av score from memory, actually might have been not too disimilar to yours.
Can you disable physx on vantage? If that was on on a non nvidia card could be hurting your scores?
Sorry cant really offer any decent advice as If I knew a good answer I would have done it myself. There are some people on here with some quite good scores so maybe they can offer some good suggestions.
Thanks for the reply. To be honest im a total newbie when it comes to scores and clocking to raise them.. Ill be happy just knowing that the system's scores are at least realistic and there is nothing slowing it down due to some technical fault. The CPU seems to look a little low to me too.

very easy to OC an i7, if you want a completely safe OC all you need to do is adjust the bclk setting in your bios. I have a 920 also and for my milder OC profile I run pretty much all stock settings except bclk changed to 175 with a x20 multiplier which gives you 3.5ghz which in reality is all you need as much higher is just for the value of saying im at 4ghz and the extra synthetic benchmark score you can get, real world performance will hardly change.
