Overclocking the 8800GTS 640MB

Hey guys, I got my new EVGA 8800GTS 640MB SuperClocked yesterday, with factory shipped 576MHz Core clock and 1700MHz effective memory clock and decided to start to try overclocking it some more.
I am using RivaTuner, the latest build.
I have gotten it to...

632MHz Core Clock and
948MHz Memory Clock (1896MHz for comparison to Newegg amounts)

Anything after this i start to get that blocky weird artifacting/random blocks popping up on the screen.
Temps are around 67C idle with the default fan speed, and around 59C Idle when i set it to 100% in Rivatuner.

This overclock has gotten me about 500 addition 3DMarks to get my 3DMark06 score to 9757 Marks with my specs below. My ultimate goal is to get to 10000 or higher, which will probably be done by OCing my E6600. unfortunately I am seeing a BIOS error (see this thread if you'd like to help :D) so cannot OC over 2.69GHz.

Anyways, unless anyone else has any other ideas, I dont think I'll be able to get any higher of an OC on my graphics card, but am pretty happy with where I am.

What are your results with overclocking the 8800 series? What have you been able to achieve? How are your temps?
