gmcq,
I would recommend you several steps:
1. Use G25 BIOS (or P04)
Done that

2. Get your FSB clock as high as possible .
Done that

3. Use 177.26 driver for you videocard. It requires some modification of nv_disp.inf file, described in 3D guru thread.

And why? I used the same drivers as I am now under the Asus and was getting excellent scores

4. Tighten your memory settings - look which ones people use
LOL - this board wont even let me go one step up from 1066, when my memory is 1333 capable.
