Not quite. They were using Pre-release drivers merely to conform within the parameters of their review. They chose to force multi-monitor gaming WITH Tri-fire, and thus had to use obsolete drivers to do so. The performance comparison is nil in this situation. Using the latest Beta Nvidia drivers vs. Pre-release AMD drivers, OF COURSE the scaling is going to be horrid for AMD.
If they had done some testing @ 2560x1600 with the latest AMD drivers, things would be MUCH closer. Oh and don't forget, there's up to 400mhz of room to OC on the 7970s as well. Would've been nice if they included an "Overclocking" section as well, to gauge performance when OC'd. I'll bet even with shoddy drivers, the 7970s would've pulled damn close to the 680s.
I own both 3 7970s AND 4 GTX 680s, and yes I have the 4 680s in my PC atm, BUT I'm also considering selling them, as I've had some stability issues that I never had with my 7970s. There is also some severe scaling issues with the 680s that have yet to be corrected. For example, I barely pull 50% per GPU on the 680s @ 2560x1440 4xAA. While it's still more than playable, there is no excuse for such low utilization when my 7970s were screaming at 99% the entire time and feeding me all the frames they could churn out. The 680s do a good job, but there's no reason why 4 680s should drop anywhere near 60 fps at this resolution, especially OC'd to 1250-1300mhz boost clock with a 3930k @ 4.8ghz.
With the recent drop in price on the 7970s, its easy to find them for 400 or less used and nice aftermarket models on ebay for a little more. It's tempting, as I'm an overclocker at heart. I'm also concerned about the 2GB of VRAM and it's degree of being future proof. All it would take is ONE new blockbuster release like BF3 that uses more than 2GB to render them obsolete IMO. Whats the use of having all of this rendering power if it can't be taken advantage of? In my opinion, the 680s should've been released with 4GB at the start. It's not like memory is in short supply.
