Hi there,
Tonester and I have ran some benchmarks with 7970 CF vs 7950 CF at the same clock speed to try to quantify the difference in today's games while the two cards are at the same clock speed. As the 7970 GHz Edition and the 7950 have quite different clocks out the box it can distort the picture about the difference between the two cards in real terms.
Of course the 7970 is faster when both are clocked up but the common myth that a 7970 can clock further than a 7950 is quite false. The point of the comparison is to show you whether when you overclock your 7950/7970s is there any point in paying the extra for the 7970s. I won't offer any advice on this because to be honest, it's down to each person individually to have a look at the difference and determine what they want to do.
Game ran:
Hitman Absolution
Tomb Raider
Bioshock Infinite
Sleeping Dogs
DiRT Showdown
Metro 2033
Benchmarks ran:
3D Mark 11
Heaven Valley
My set up is in my signature as is Tonester's. My CPU was clocked to 4.4 GHz but the extra clock speed on Tonester's CPU is unlikely to affect the results that much other than in 3D Mark 11. All tests ran at 1920x1080 and 2560x1440 will follow.
You can take the results as either a simple clock for clock comparison or as a guide to how the cards perform in 'x' game. It's up to you
.
7950 CF @ 1100/1500:
7970 CF @ 1100/1500:
So to compare the clock for clock difference (average FPS) are as follows:
Bioshock Infinite: 3.8%
DiRT Showdown: 2.2%
Hitman Absolution: 2.7%
Metro 2033: -1.7% (potential testing anomaly as the benchmark is a bit sketchy)
Sleeping Dogs: 3.8%
Tomb Raider: 4%
3D Mark 11: 5.8%
Heaven Valley: 4.7%

. Need to clean it all out but I only run 1075/1450 for 24/7 really.
it was really really easy to get my 7970's to 1150 on stock volts, and only a tiny tweak for 1250.
