My power supply is an XFX Black edition 750W 80+ Gold as I stated earlier, I want to know if it is good enough to handle 2x 7970 Ghz with my rig, or do I need to get a new power supply with more wattage?
CPU: AMD FX-8350 - OC @ 4,7Ghz 1.464V
CPU Cooling: Corsair H100i
MB: Asus Crosshair V Formula Z
RAM: Corsair Dominator Platinum 16GB (2x8GB)
HDD: Samsung 840 SSD 240GB, 2x WD Caviar Black 1TB
CD/DVD: Asus cd/dvd-rw E-green
FANS: 3x120mm 1x140mm 1x200mm. (and 2x120mm on the H100i)
PSU: XFX ProSeries Black Edition 750W 80+ Gold
Please help =)!

Best solution
It should power such a system sufficiently, but perhaps just barely under maximum load.
Using the eXtreme PSU Calculator, I plugged in your components and it calculated the system to use 725W at 100% load. It then recommended a 775W unit. At the recommended 90% load setting, it claimed the power consumption would be 631W, and recommended a 681W unit.
While it's rare that a system is ever stressed to 100%, it can happen under some benchmarking conditions. (Such as simultaneous Prime95 and Furmark testing.) Using a 750W unit, you might want to avoid full-load simultaneous stress-tests of the CPU and GPU subsystems, especially if both end up overclocked.

But if I run them separately (prime95, Furmark) I should be fine? I mostly use this rig to run games, demanding games (bf3/bf4 etc), for games it should be fine right?

Gaming or testing it will be completely fine.

I don't foresee any problems during normal usage. I was just putting forward a word of caution regarding simultaneous CPU & GPU stress testing. Under that condition, you could end up pushing the PSU to (or at least toward) its limit.
