differences in scores

[ame]

Hi all
I have a question.
Why the scores in benchmark charts and when i browse specifications are different.
for example when I check average score in 3dmark vantage for HD4870x2 in specification It's quite different from what I see on the 3D mark Vantage chart.
just wonder...

and why score for 3x 9800GTX on vantage chart is higher than the record in this benchmark for this setup.

Can you provide any links?

OK. For example HD4870x2 in 3dmark vantage.

So, here I took this result:
http://hwbot.org/hardware.statistics.do?applicationId=17#chart
- 16098.74

and here I saw another result, slightly different:
http://hwbot.org/browseHardwareVideoCards.do?gpuFamilyId=179
- 15976.562

So I wonder what's the difference, because as I guess they are the average results from all benchmark scores.

good question; RB should have the answer for that;
