Guru3D has done an interesting overclocking guide on the 7970.

This card overclocks like a beast with hardly any increase in temps or TDP with a really good performance increase, making it even better still and pulling away from the 580 even more.
I wouldn't call that really interesting.
Benchmarking a load of old games, mostly crap, that you'd have completed a long time ago. And more FPS (when most of the cards on show never went under 30) is not exactly going to motivate you to want to play them all again really.
Buying one for running all the games you can already run is a bit silly really.
I actually sat down and thought about it the other day. If you were one of these type that buys every new GPU then it goes something like this...
Xbox 360. £300 or so at launch. 5 years old, improved very well. It's finally showing its age, but the difference between it now and when it released is remarkable. Killer apps? many. Too many to list.
Several GPUs over 5 years. Total cost? about £2000. Difference? well, they are still using Crysis to compare the cards. Killer apps? since Crysis - 0.
To be completely honest once there is a console that can do 4XFSAA I am ditching PC gaming for good. It's a seriously sinking ship.
Most notable game this year? Battlefield 3. Takes enormous amounts of vram to run and isn't even exclusive.
For the most part it's been utter crap like NFS : The runs. With a 30 FPS cap, just to remind us how much they care about people who game on a PC.
IE - they couldn't give a rat's.
