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.
 
Guru3D uses the following games in their test suite: Hard Reset, COD-MW2, Far Cry 2, ANNO 1404, Metro 2033, ANNO 2070, BFBC2, BF3, Crysis 2, AvP, Lost Planet 2. Total fps (summing fps in each game @ 1920 x 1200) are tabulated below along with their cost in dollars per frame @ 1920 x 1200:

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
670 DCII gets 999 fps for $420 at a cost of $0.42 per frame
670 gets 917 fps for $400 at a cost of $0.44 per frame
7950 gets 746 fps for $330 at a cost of $0.44 per frame
7970 DCII gets 924 fps for $415 at a cost of $0.45 per frame
680 DCII gets 1077 fps for $520 at a cost of $0.48 per frame
7970 gets 872 fps for $420 at a cost of $0.48 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.

A 500 watter is ya gonna stay with a single card, 750 watter if ya going SLI or CF

Corsair TX series, Antec HCG or HCP, XFX Core Edition would be my 2nd choices

Corsair HX or Seasonic X series would be my 1st

Any suggestions? I'm going to place the order for my parts tomorrow morning.
