Upgrading Need Opinions AND Help

[clearfork4pk1ng]

Alright so basically i'm planning to upgrade from my current build and im trying to figure out if the PSU that I am currently using is going to be enough to get the job done. I do a pretty good amount of gaming on this computer and intend to in the future. My displays will remain dual monitor VGA outputs.

CPU: AMD Athlon 2x 270e Regor ---------------> AMD FX 8350 Black Edition

GPU: HIS Radeon 6750HD 1GB DDR5 ------------> Sapphire Radeon R9 270X 2GB DDR5

MOBO: MSI 760GM-P23 (FX) --------------------> ASUS M5A97 R2.0 ATX AMD 970

PSU: Corsair 600w Builder Series ---------------> ? ? ? ? ?

Like I stated above, I would like to know if I will be needing to upgrade my power supply or not. And I wouldnt mind some opinions on the specs I will be upgrading to! Thanks as always guys

I'd change your processor upgrade to an FX-6300 and pour more money into your video card.

Well I've already got the motherboard and GPU that I have stated above. I'm looking to keep my PSU if I can. If need be i have absolutely no problem replacing it.
