I'll be playing Skyrim, World of Warcraft, Assassin's Creed 3, lots of other games probably like Battlefield 3, maybe Crysis 2/3,
I'll be gaming at 1920 x 1080
Idk if i'm going to overclock, i'm pretty sure some of these cards are factory overclocked
Both cards are overkill for skyrim, WoW, and AC3. Both are about even in BF3 and Crysis 2. They were about even in the Crysis 3 alpha as well.
Assuming the 7970 GHz is cheaper, it's probably the better buy unless you care a lot about power consumption/noise (the 680 will draw a bit less power and be a bit quieter most likely, depending on the model).
Both cards would do very well in any games. It's just a matter of few more FPS in different games. For battlefield 3 and Crysis games, nvidia cards are gonna perform a little bit better. I've had way too many problems with past ATI cards due to their drivers. (Latest ATI card I owned: HD 7950, then I switched to a GTX 670) If prices are close, I would go for the GTX 680.
I would stick with just a normal 7970 if you can find it for around 400 bucks. Last week they had a XFX 7970 for 329.00 with 3 games so that would be a great deal from Tigerdirect. Check out toms recent article on best graphic cards for the money right now. I have a stock 7970 right now and play all games without even overclocking yet.
This is a pretty good article which provides recent benchmarks. It seems like 7970 has the advantage in most of them. However I doubt the difference in FPS would be appreciable. It would probably be worth getting the 7970 just for the extra GB of ram alone.
The new Catalyst 12.11 beta drivers delivered major performance gains in many popular games such as Battlefield 3, Borderlands 2, Civilization V, Skyrim, Sleeping Dogs and StarCraft II. While most titles ran around 10% faster depending on their settings, Battlefield 3 was 20 to 30% faster.
Around the same time, Nvidia released a new beta driver of its own (GeForce 310.33) which claimed modest gains for the GTX 680 and GTX 660 in several titles, and this driver has since been replaced by the GeForce 310.61 update, which made further performance enhancements. This is what we'll be testing today.
With updated pricing and performance across the board, we figured it would be worth revisiting both company's offerings to see where you should spend your hard-earned cash this holiday season and into early next year.
I had the same choice as you had just last week, it was either 2x GTX 680 or 2x Ghz 7970.. I wen't with the 7970's due to the reason of it's overclocking capabilities, and that the GTX 680's overclocking potential was cut off from nVidia. I can say that the 7970 will not disappoint, it's simply a fantastic card! When disabling crossfire and running just the single 7970, I can comfortably say I can run BF3 at Ultra perfectly smooth!

Considering this exact topic is covered, it's really disrespectful to all the hard work the guys at Tom's do reviewing hardware.
