1. 
Great quick overview guys!

Still, I don't think Zotac is the fastest. There are at least 2 other GTX670 cards that can go head-to-head against it, especially once overclocking is considered:

1) GTX670-DC2T-2GD5 (Asus Direct CUII) = GPU Boost 1137mhz

2) MSI GTX670 TwinFrozr IV Power Edition = GPU Boost 1079
http://www.newegg.com/Pro...aspx?Item=N82E16814127685

Most importantly, please test the GTX670 Overclocked vs. GTX680 Overclocked vs. HD7970 Overclocked while using the fastest drivers from both camps (304.48 for NV and 12.7 Beta for AMD). 12.6 Drivers don't include the added performance boost that's included in 12.7 Betas:

The reference HD7970 Ghz Edition will be loud though since that XT2 Tahiti chip is really meant for after market cards and the reference HD7970 blower is lousy. Looking forward to your review. Maybe you should include Sapphire Dual-X HD7970 OC since those cards scale > 1200mhz at 1.25-1.3V, have cooling for the GDDR5 and are one of the quieter HD7970 offerings based on your testing.

Memory = 6008 Mhz, 10% slower then Zotac.

All slower then Zotac.

12.6 Drivers don't include the added performance boost that's included in 12.7 Betas:

I have tested it, there is no boost on 12.7 Catalyst.

Original HD 7970 GHZ Edition we will test in the future articles.

Really? Hmm...a lot of other websites are reporting performance increases in Dirt 3, SKYRIM, Batman AC and Battlefield 3. For NV as well, there is a huge increase in Shogun 2:

That's why I recommended that if you have time you should use the latest drivers

Here's the full list of expected increases for Cats 12.7 (which are likely all best-case scenarios though):

Up to 25% Skyrim
Up to 6% in Crysis 2
Up to 20% in Total War: Shogun 2
Up to 3.3% in Battlefield 3
Up to 6.9% In 3DMarkā„¢ 11
Up to 4.8% in Aliens vs. Predator
Up to 6.5% in Batman: Arkham City
Up to 8% in Crysis Warhead
Up to 7.2% in F1 2010
Up to 8% in Just Cause 2
Up to 12% in Wolfenstein MP

If you are going to benchmark HD7970 GE from scratch, might as well use 12.7s! Looking forward to your review either way.

My Sapphire Dual-X does 1150mhz @ 1.174V using MSI Afterburner 49-51% fan speed @ 70*C at load. I decided not to wait for GE cards since I am thinking that AMD using the driver to dynamically adjust the voltage beyond 1.2V at load. I have a feeling this is where most of the overclocking headroom comes from for GE revision cards. The increased power consumption and noise level penalty (the reference cooler is way too loud to cope with 1150+mhz overclocks I feel) does not seem worth it to pay $499 over getting a $450-470 non-reference HD7970 with a nice after market cooler.

On 304.48 NVIDIA - yes, some performance increases in all games, but on 12.7 beta AMD no performance increases. Try it.
