Say I bought

GIGABYTE GV-R795WF3-3GD Radeon HD 7950 3GB 384-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card
Z9 ATX Mid Tower Computer Case or possible NZXT 410 Phantom case
i5-3570k with hyper 212 fan
ASRock Z77 Extreme4 ATX LGA1155 Motherboard

and used (what I currently own)

8gb Ballistix ddr3 1600 ram
120gb agility 3 ssd
250gb hard drive
cd drive

And planned to overclock the i5, maybe overclock the 7950 now or later. Can you recommend me a PSU that is $80 or less that would allow all of that and the possible overclocking?

I'm trying to future proof this sytem for the next 3 years or so. I currently have a 5850, and I have been recommended either the 7870 or 7950.

660 PE gets 851 fps for $300 at a cost of $0.35 per frame
7870 gets 701 fps for $280 at a cost of $0.40 per frame

7970 GHz gets 952 fps for $470 at a cost of $0.49 per frame
680 gets 989 fps for $500 at a cost of $0.51 per frame

Of course other sites with different test suites will come up with different numbers, but I'd also consider the 660 Ti in your price category.
