You can OC further and you can unlock some of the 7950's shaders and cores so it comes closer to the 7970's specs

No, you can not unlock the shaders.

It has better voltage regulation, better power delivery, and more headroom to overclock (8+6 pin delivers more power than 6+6 pin, increasing max TDP). However the chance to get a bad overclock is the same, its not really a huge chance. Its just nice to have. The best 7950 overclock was from a Gigabyte WF3 which is a 6+6 pin.

Alright thanks everyone. Now which 7950 should I get? My original choice was the gigabyte 7950 windforce, but recently the HIS iceq 7950 came back in stock.

gigabyte HD 7950 comes with newer BIOS versions and locked voltage . 1 ghz boost clocks. should run easily at 1100 mhz. but the lack of voltage control is disappointing.

sapphire HD 7950 boost (11196-16-20G) has a reference AMD PCB design. unlocked voltage and a good cooler. good vrm heatsink cooling. 29 cm long. make sure your case can fit it. superbiiz has a good price. with a $7 OFF with code SBZSHAKE valid till 3/11. USD 300 (280 with rebate)

his hd 7950 iceq boost does not have vrm cooling. the his hd 7950 iceq x2 boost has vrm cooling but is out of stock at newegg.

I really wish I would of gotten paid in time to buy that 7950 when it was $290. Anyway though, I've been trying to stick with newegg because of the free 2 day shipping from the shoprunner trial, but superbiz has a good deal..hmm.

Edit: What do you think of this 7950

From what I've read, it's basically the same as the one you linked, except it's smaller.

its a custom PCB. so no full cover waterblocks. no VRM temp sensors. has unlocked voltage and a good cooler. 27cm long. shorter than the ref design which is 29 cm long. feedback seems to be positive.
