My other specs are:
E6600 @ 3.0ghz
2x 1gb crucial ballistix tracer ddr2 1000
asus p5b deluxe
raptor 74gb
and then 512mb 8800gts
I can run it fine now, I had the latest drivers too(with my 7600gt), I think my card was just overheating because I had kind of a small case and no outtake fan at the back just a blowhole so there wasn't much airflow and the chipset idled at like 45*C, but that is no longer an issue because I got a new case which has plenty of room and airflow
Yeah The only things I'm missing from the hack I've applied, is better objects (not much difference to be honest), smooth shadows, and object motion blurring. The scene motion blurring is still there though.
