I have a Ultra X-Finity 600 watt.

so i will not have to buy a new psu.

Any help will be appreciated .

Thanks .

Rest of my rig

AMD 939 4000
GIGABYTE k8N- Sli
SUPER TALENT x512
BFG 6600GT

depending on the rest of your rig i would say 8800gts would be just fine even a gtx. my psu is only 33 amps and its fine.

Should be enough, I don't think you'll have any trouble.:)
