Is it normal result for this PC?

I had run a 3dmark06 benchmark test on my brother's pc but I was suprised that I seems to receive poor results which the total points are 14878 with the system listed below:
Core2Quad Q8200, OC to 2.8ghz
3gb of ram
Asus Radeon HD5850 1gb ddr5

While my own system receive a total benchmark points of 14442 with
Core2duo E8400 OC to 3.6ghz
3gb of ram
Zotac 9800gtx+ 512mb ddr3

The question is, why does the difference is so little (436 points difference) as the HD5850 is a gpu that kick 9800gtx+ ass? Is this normal for my brother's system to have such result? Besides, the other components/hardwares in both PCs are similar.

3dmark06 is HEAVILY CPU dependent. This is as to be expected.

From looking at some results from similar systems on the Futuremark website, the score seems slightly low, but definitely in the right ballpark. Why are you both running 3gb of RAM in systems that support dual-channel RAM? I bet you would see a slight increase in score by switching to a dual-channel setup.

Thanks for the info. The reasons that we don't use dual channel is because I cannot feel the differences in real time performance which I tried last time with 1gb + 1gb compare to a single 2gb ram.

Run vantage, there should be a bigger difference there.

I see now that it is the cpu is causing the low benchmark results. The pc is still running good, I not planning to change the processor anytime soon.:)
Thanks for helping me to clear my doubt guys.
