sweet thanks man. I was reading the review of it on newegg .....a guy said this:
Other Thoughts: cards are very well built. consider a sli certified psu even if you are planing to run only one they have a minimum psu req of 400w and a 12v 26amp current rating
so i guess i should get a power supply of 400w 12v 26amp right? ....but do i have a sli certified psu?
