-corsair vengeance 2x4gb 240 pin DDR3
-motherboard : GIGABYTE GA-B75M-D3H

None - your current 650 will be fine.

Are you adding an HD7970 to an existing one in CrossFire-X or putting in one graphics card only. If adding an additional card, more power is suggested. If simply putting in one only, the TX650 should perform wonderfully

no need to. your PSU is plenty fine for that.

if you ever add a second 7970, then you'll be looking to get into an 800w.

for now, keep what you have :0
