Have you done any gaming with the card? If the card plays games at your desired quality settings at smooth framerates, what difference does it make that the benchmark numbers are a little less than hardware sites report. I get sick of people that buy cards and high-end systems just to benchmark (although I'm not saying that you are one of those people).
No i'm not buying card for 3Dmark but it is a utility tu measure the performance of the GPU. In the game it is super fast and no quality issue or high temp. But i was wondering if anyone how own the same card has the same score...Quad Core mabe make the difference...and if it is, i will not buy a quad core just for the 13K..is working fine with 11.5K
Your cpu score is in line with a stock 6750 as is your SM 2.0 but your 3.0 score is lower than an 8800 GT OC 512 running at 660/950(1900)which is 6000+. Gainward is at 650/950 so there shouldn't be that much difference ...you may have driver issues.
