You could get away with a 500watt psu.

A 600w is more than enough. 

 

The EVGA GS and G2 650W PSUs are good. (a GS 550w would do as well)

Yep, might as well. It will give you more room for future upgrades.

I would get 1 970 now then upgrade your cpu and mobo to an I5 before getting a second 970.

Yes, you should definitely upgrade the CPU before getting a second 970

 

EVGA's 750W B2 is good for the money, check out offerings from XFX as well as their PSUs are going on sale almost everywhere.
