I'm looking at taking 2 of the 6870's for xfire. What PSU would I need? is 650 enough?

Also can someone confirm that my mobo can't take SLI but CAN take xfire?
 
Yes 650w will be fine aslong as you don't overclock the cards to be on the safe side, depending on the age of the PSU you have. They say 600w is what is required for 2 x 6870 in crossfire.
