i bought a whole new computer.
opteron 144 1.8ghz (oc'ed to 2.8ghz)
asus a8n-e
rosewill 550watt dual rail psu
patriot pc3200 2x1gb 5-2-3-2
2x160gb wd sata ii raid 0
geforce 7900gt 445/660 (oc'ed to 525/770)
and along with all your usual components
max score i managed was 9.3k for 3dmark2005. i was really expecting more, but i guess its possible with a more powerful cpu.
i also had the abit an8 32x and enermax sli psu, which are some of top of the line products. i didnt has sli at the moment, but i wasnt impressed with the mobo at all. my asus ran more stable and i didnt have to raise voltage to overclock. the abit has some problems and they havent release a new bios since it was first released. it was a big waste of money.
