Why?

Well a CPU does not have the limitations a dual GPU can have, microstutter, dodgy xfire/SLI scaling, games needing profiles, driver problems that are not there with a single GPU. So I would treat a single GPU in a different category to a dual GPU because of the mentioned draw backs. Personally I doubt we will ever see a dual GPU from Nvidia again, they will just let people go SLI with cards of their choice, I mean if you can afford a high end dual GPU, you are certainly going to have the mobo and PSU to do SLI.

Fair point. Why I am comparing 5870 vs 580? and not 5970?
Because I just upgraded from 5870 to 580, and these tests were run to compare the two card and to see if the upgrade was worth it or not.
So far I have gained 50% over an overclocked 5870.
Sadly I havent got 5970 to compare it againts 580, and if I did i wouldnt of got the 580 because the change would be minimal. I think the demo runs at 1080p.
Fair play and thank you for a very honest answer!
Of course it does, dual processor server boards overcame those problems years ago!
Besides you can still crossfire dual gpu ATI cards so your last point is totally worthless.
5970 vs 580gtx is a perfectly resonable comparisons. The people that cry "ahh its 2gpus vs 1" is absolute nosense. They are both single cards that take up a single PCI_EX socket.
Personally I dont like SLI or Crossfire. Because its not without its faults. But if 5970 could be bought for £300 I wouldnt of bought a 580GTX.

just bought myself a 580! can't wait to try it out. my 480 will be for sale shortly 
btw i bought it from that well known auction site for £429 but for some reason earned myself £223 worth of vouchers when I bought it. so it's basically half price! lolocaust...
anyway will be getting some direct 480>580 benchies up for you guys soon. should be with me in a couple of days.

There is a thread on this over on xs forums: Some do fit but you need to add extra thermal pads on the ram and some of the vrm's.

I did the same thing saw the £223 worth of points and couldn't resist
Hope its not a mistake from the well known auction site 
Have not had to time to bench any games yet as it's a fresh install of the OS and all my stuff is on steam. Today instead I had a look at the beta Afterburner and discovered only 3 of the voltages are useful to me 1.0v, 1.013v, and 1.025v. If you set any of the gpu's to voltages in between they won't stick. For example, both my gpu's have a default voltage of 1.0v (0.98 reported by GPU-Z) and 1.013v (1.010v according to GPU-Z). If I try to raise the 1st GPU's voltage it will revert back to 1.0v until I set it greater then 1.09v, then it instantly jumps to 1.013v. Same with 2nd GPU, if I raise the voltage past 1.013v, it reverts back to 1.013v until I get to around 1.02, then it jumps to 1.025v.
Anyway, I've found having both gpu's at 1.013v will let me bring my cores up to 833mhz and they will run Heaven reliably with no artifacts. At around 837mhz things get hairy and I see the odd artifact. Over 840mhz, artifacting is worse, and at 850mhz even at 1.025v Heaven won't run reliably. I can loop it once or twice but eventually the nvidia driver stops responding. Also at 850mhz the fans are noticeably louder.
One thing I have noted is the gpu's will never go over 85 degrees regardless of voltage or overclock. The fans always kick in to compensate. I think the sweetspot for me is probably 833mhz to be honest. At that point I never see temps over 78-80 degrees, which is about 3-7 degrees higher then stock. Also fans are quietish.
Below is the most recent Heaven bench I ran at 833mhz core. Resolution is 2560x1600. The cpu is clocked at 4.16ghz, not great, but not bad considering I am managing to keep my 12gig ddr3 running at 2000mhz CAS6. I needed 1.3v vcore (1.265 underload with LLC set to 50%), and 1.35 VTT.

as you would expect Nvidia have the top single GPU card and it looks a corker and for the people with the money and the need (high res) it seems the way to go for a single card solution, i cant see AMD beating this with a single GPU.
For me personally its always about the cards that cost £200ish at the moment if i was in the market i would probably go for the 470.
Im pleased that it has got interesting again

People who don't have GTX480 can have it for almost £100 cheaper than GTX580. Which is a problem really as said 480 is already a little on the expensive considering prices of both HD6870 and GTX470 and the performance differences.
OK got some 1080p results done, added Dirt 2 and crysis results.
480@850 core/2000 mem
Heres a 860mhz-2350 580gtx which is not really a good overclocker taking an overclocked 480gtx to town by some 15%.
And all at the same time doing it quieter and more efficently than before.
