I am getting a 2nd 7950, what type PSU should I get?

I have  http://www.amazon.com/gp/product/B00CPLI74S/ref=s9_simh_gw_p147_d7_i4?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-5&pf_rd_r=1BJESW2WQVK0D4HV478J&pf_rd_t=101&pf_rd_p=470938731&pf_rd_i=507846 Sapphire Dual X 7950. However I want to crossfire. My two questions is should I get the same card or maybe the MSI 7950. Also what kind of Power Supply unit should I get. I was thinking the Cooler Master 1000V series however people can put their input in also.

 

This is my current specs:

 

CASE: GAMMA Classic Series ATX Mid Tower Interior Steel Chassis (Black)

CPU: AMD FX-8120 8-Core Black Edition Processor Socket AM3+ - FD8120FRGUBOX

RAM: AMD Memory Performance Edition Kit 8 Dual Channel Kit DDR3 1333 (PC3 10666) 240-Pin SDRAM AP38G1338U2K

Motherboard: ASUS M5A97 R2.0 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX AMD Motherboard

GPU:Sapphire 7950 Dual X

POWER: Corsair Enthusiast Series 650-Watt 80 Plus Bronze Certified Power Supply Compatible with Core i3, i5, i7 and platforms - TX650

120GB SSD samsung

500GB WD blue

 

You don't need any more wattage, but if you are looking to spend money on a new PSU, I can't stop you. The TX650 isn't exactly amazing, by any stretch of the mind, but it isn't bad.

I need to know a budget, but as for type, get an ATX 12V PSU with a single 12V rail.

Also, moved to the correct forum :)

PSU, not GPU.

I dont think 650w will be enough for crossfire + a fx 8xxx series cpu, but I could be wrong.

It will be, but 700 to 750W would be better in terms of load in regards to efficiency.

the psu i have also does not allow me to add a second card. Also I do overclock my 8120 too 3.8. and also I do some overclocking on my card when its needed. The price to spend on a new powersupply is $200 or less
