I'll put a couple of posts in here from the 480 thread. That way it clears it up.
Firstly this one on the 2nd March. 6 weeks before I got my 480s and still owned my 7970.
How well do these handle BF3? What current cards do they compare too? Does anyone have a BF3 benchmark?
Don't have BF3 benchmarks.
But they score just under 10k in 3dm11 (P) at stock with a stock 950.
They score 30,000 3dmarks in Vantage in the same rig.
So when compared to a 7950, say, they are waaay faster. Basically at stock they are 20% faster than my 7970 @ 1000mhz in the same spec rig in 3dm11.
Just make sure you can space them out properly.
between 6950/6970 performance
Hmm. Don't think so ! The 480 is right around bang on a 570, only it has more vram. Overclock a 480? tada.
And then this one.
You say overclock, I hope you have your own generator and ear muffs.
At stock they use 4w more than a 580. And the 580 has a TDP throttle.
Fermi got a lot of bad press due to heat and noise and so on. Most of it though? well, was the way forward. No one batted and eyelid when the 6950 and 6970 came out and were also red hot, loud and guzzled power.
So IMO? they're no worse than any other DX11 card. Sure the 5870 and 5850 used a fair chunk less power but ATI couldn't keep things at those levels. Even the 79xx cards pig down watts when you overclock them.
Nvidia's adaptive performance driver took care of most of the heat issues. My friend's SLI idle at 41 and 42c. That was another trick that ATI had used with the 5 series. They clocked down. As soon as Nvidia cottoned on to that they did the same.

Oddly enough it seems to be pretty much the same thing this thread has said all along. Funny that eh?
Not beating an 1174mv on 12.4 drivers 7970 you're not, but agree you're close. But I won't be trading in mine for some old oil burners just yet.
So you are actually saying that your 7970 is faster than 480 SLI when the whole world, facts and all disagree with you?
As for me being close? if I replaced my CPU with a spangly new one and ran the tests again they would be exactly the same. Simply because no matter what scenario they are in the 7970 simply isn't as fast as 480 SLI.
And, I have been quite tame with the clocks too. I read that a 480 @ 840mhz is bang level with a GTX 580. Don't tell us though Dave ! a single 7970 is faster than SLI 580s.
