Depends on your cooling setup. If you're going open air, get the double fan cards as they circulate better at the expense of exhausting the heat. If going case and noise isn't an issue, exhausting cards.

Ah that's very good advice. So the other 2 (gigabyte and xfx) push the air everywhere mostly?
Where as the powercolor and sapphire force it out the rear?

I'm currently open air, but would like to fit this next batch into a case... "exhausting" cards sound much better to me.

The open air blows will typically exhaust about 25% of the heat, and the single blowers 70%. It can make quite a difference if you're trying to mash 3 in a case.

Nothing beats the sapphire 4Ls. Amazing cards.

+1

+2. Running 3 of them at 1ghz core at 1000mv vcore. They are loud like any reference design squirrel fan, but they run cool. Also, not voltage locked unlike the latest batches of the Gigabyte 3 fan card. XFX card is absolute crap. Belongs in a "Worst 7950 card right now" thread. I can not speak to the PowerColor.

Im running both the Gigbyte Radeon HD 7950 and the Sapphire HD 7950. Out of the box the Gigbyte Radeon HD 7950 outperforms the Sapphire and runs cooler.

Gigbyte Radeon HD 7950 - 560 kh/s, 60-70 deg (no OC)
Sapphire HD 7950 - 485 kh/s, 70-80 deg (no OC)

using the same settings in cgminer for both cards (litecoin)

The Sapphire can run very cool (~55 deg) with the fan at 85%, but it sounds like a jet engine

The Gigbyte Radeon HD 7950 runs silently around 65 deg with the 3 cooling fan design

I have the Sapphire currently, even at 65% the thing is loud.

Since this will be mounted in a case, is there a concern with the gigabyte not exhausting enough air..? Like the poster above mentioned. Seeing as some of the air is dispersed into the case, and not forced out the back.

Last question, have you attempted any overclocking? Do you mind posting your cgminer input for your sapphire?

I agree with Bitrocket....better performance from the Gigabyte 7950s vs Sapphire 7950s.

I've had 2 sapphire 4Ls and they've both been crap. Run hot as hell, noisy (lil quieter in a case but still noisy) and unless you run it by itself, you better have good case airflow to assist the blower. Not to mention both cards thus far began IMMEDIATELY artifacting my desktop while mining as the display card.

Maybe I'm just unlucky but that's been my experience. Double d has bad reviews, no personal experience.

Everyone seems to have their best pick of cards, it's rough shuffling through all the search results.. I currently have 3 SAPPHIRE 100352-4L and looking to build a second rig.. I'd like to choose the best card for maximum hashes.

These seem to be the top 4 choices.
