if you are considering xfire for the 290 later on, then the 750w would be the minimum. might even look into 850w for that use. the 290 is a 300w gpu and 2 of them plus the system would be pushing 750w to it's limits even with a quality psu.

if you are serious about xfire 290's then i would seriously look at 850w's
