Assuming the system in your signature is the one that you run the test on,
A quick search on the benchmark records for 3d mark shows that the top score for this CPU/GPU pairing is 8,123. That's with a hefty overclock though, and quickly skimming through suggests that most scores above 7,000 - and a good deal below - have the processor clocked to as much as 5.1 Ghz. That's not even accounting for the differences in GPU and potentially driver version between dates.
I'd say, given the evidence, that your results are well within the expected range. Naturally, you could play the benchmark game and try for a higher clock and see if that would bump the score up any, but providing there are no issues with day to day I wouldn't worry at all.
