Two 6870s in Crossfire is hardly an upgrade IMO mate. Infact, the 6870 sat between the 5850 and 5870 and isn't even as fast as a 5870.
Sorry but two 6870's are on par with a 7970
Sorry but they're not.
They're not even in the same class, let alone the same league.
They're totally crippled by 1gb of vram for a start.
Wow. That's me convinced !
One whole FPS.
What you seem to have completely forgotten is that Crossfire X is driver dependent. But, seeing as you seem incapable of understanding that here, here is your 6870 CF when put against a GTX 580 in Crysis Warhead.

Now any one with a brain capable of understanding it would know that Crossfire X is obviously not working there. And, if that can happen once (and it will) during the entire ownership of a multiple GPU set up it automatically totally fails the multi GPU set up.
Only very silly people go out and buy a crude setup like that so they can say it's faster than a real, top end GPU.
Minimum frame rate, could be a one second stutter, use this "brain" you're talking about.
The problem here is you are not talking to a gullible idiot who doesn't know first hand what a PITA Crossfire can be. Nor some one who isn't aware that a tiny handfu....
5770's are half the spec of a 5870, at best (And yes, in some occasions they offered on better than but that wasn't the norm) are on par with the 5870, not sure why you'd get two expecting 5870 besting performance.
I've had a few multi gpu set ups, they've been fine.
But the 5770 was exactly half the spec the 5870's were...
800 shaders, 128 bit bus.
5870 was 1600 shaders 256 bit bus.
Your experience of crossfire was a bad one because you expected something unrealistic.
YUP ! damn right I expected something unrealistic.
I expected it to work. How totally, terribly bloody stupid of me !
But Crossfire does work......
