I just wanted to share my OC results for both 8800 gt and 9600 gt systems that I have. I built the 9600gt system for my Friend, and wanted to compare my 8800gt system with the new 9600gt System. Both machines are of Similar configuration except for the GPU. Here are the results:

System Profile:
Q6600 at 3.4ghz
P5K Deluxe Mobo

8800gt System (Quad-Fusion)
3DMark06: 14541

XFX 8800gt
Stock: 640/1600/900
Max Stable OC: 730/1825/1050
Accelero S1 Rev.2 w/ 120mm fan
Temp>> Idle:38c Load: 47c

9600gt System (Magnus-Machine)
3DMark06: 13312

XFX 9600gt
Stock: 650/1600/900
Max Stable OC: 821/2105/1050
Thermalright HR-03 GT w/ 92mm Fan
Temp>> Idle:33c Load: 46c

8800gt System (Quad-Fusion)  3DMark06: 14541

9600gt System (Magnus-Machine) 3DMark06: 13312

Only Configuration Differences between the two systems were:
8800gt powered by Rosewill Xtreme 750w, CPU cooled by Zalman 9700NT, Antec 900 Case
9600gt powered by PC Power & Cooling Silencer 610W, CPU cooled by Thermalright Ultra-120 eXtreme with Scythe 110cfm fan, Raidmax Smilodon Case

While similar systems, the scores could very well vary quite a bit.
 
I have a Q6600 Oced to 3.15GHz and a 8800GTS 320MB Oc'ed to 680/1615/1050. The highest score I've ever seen was 13444, which is higher than your friend.

I just built the new system,, So I will check the settings and do  more runs

Now do some real-world benchies
