So these are my results from my 10.5.1 install:

Zeph 10.5.1
Asus A8N5K Mainboard (nForce 4)
Athlon 64 X2 4200+ (939)
2GB DDR400 (Corsair)
ATi x1600 Pro 512mb (only 256mb detected) QE/CI working
2 WD 120gb Sata II drives
1 Hitachi 80gb 2.5" laptop drive

And here's my current setup:

Changed is a GeForce 8600GTS instead of the x1600 and the 1 120gb Sata drives are in a striped array.
Considerable improvement for the hard drive score.

One thing I'm kind of wondering, is why the OpenGL test is lower for the 8600GTS than the x1600?
