Power Supply Upgrade Suggestions

Greetings,

A little while ago i posted a topic asking for the best upgrade to my PC for $300, and i was told to pick up a Radeon 7950 and a better power supply (Mine currently i only 430 Watts), but the only problem is that i don't know very much about PSUs, and i assumed you guys would know far more than me.  THe 7950 I'm picking up (The Sapphire version) is $210 so i need a power supply, preferably over 700 watts due to possible upgrading (Upgrading FX-6100 to something like a FX-8350) and overclocking.  Thanks a lot.

Current PC Specs:

CPU: AMD FX-6100 3.30 GHz Six-Core

MoBo:GIGABYTE GA-970A-D3

GPU: AMD Radeon HD 7770 1GB

Memory: 8gb(4GBx2)@ 1600MHz

Power Supply: 430 Watts - Corsair CX430

OS: Windows 7 Professional

CPU Cooling: Asetek 510LC Liquid Cooling System 120MM Radiator & Fan

Case: Thermaltake Commander Mid-Tower Gaming Case

I have never had any rosewill parts but from the specs and this review it looks like it will serve you just fine

Any Seasonic or Corsair PSU will serve you well! They both have a lot of offerings at different wattages and different price points. I have a Corsair RM 850 powering my FX 6350 and Crossfired 7950s.
