Also Slimebeast... Metro 2033 maxed out, on DX 11 at 1080p, with Physx on and 3D vision on, at 60 fps... Next gen consoles will be VERY lucky to come close to that level of performance.
You need a GTX480 SLI and I7 to achieve this today...which is 2000 dollars worth of gear.

The biggest factors in that costing are various inefficiencies.
- According to Carmack you need 1/3rd the performance to run at 30FPS over 60FPS at the same image quality. Most consoles will be forced to run 3D content at 1280/720 @60FPS due to HDMI 1.4 limitations.
In any case, IMO probably the worst thing which happened for PC-gaming was the allowance of cards to draw > 150W of power. It would have probably been better had GPUs themselves been limited to the 75W PCI-E limit for the overall PC-gaming market, not the whims of the high end enthusiasts.

What do you mean by HDMI limitation ? We can run any PC monitor through HDMI 1.3 in 1920x1080p@60fps currently.
And I don't agree about high power GPUs. If we were limited to 75W we would be at level of radeon 5750 which is low end of today cards. Now 150W ceiling is more resonable as that is 5850/GTX460 which provides good performance but if people are willing to pay for 200W monsters why should anyone stop them. I have GTX470 and i don't find any problems with it - altrough of course such card is enthusiast level gear and requirers computer case with above average wentilation.

You can't run 3D at more than 1280 by 720 due to how the HDMI 1.4 spec operates. Its not a bandwidth limitation.
The reason why they should have limited GPU power?
1. It means that instead of simply tacking on more functional units they would have been forced to make them a lot more efficient and this would translate to improved performance from bottom to top.
2. It means that PC game developers would be able to target a more consistant specification and there wouldn't be as great a spread between the highest end and the lowest end GPU on the market.

That's for 3D. Normal picture can go to 1080p without problems.
Ad1. And they are working on power efficiency - radeon 5770 brings power similar to 4870 at 100W instead of 180, radeon 5870 has performance equal to pair of 4870 in 186W TDP instead of 360Watts.
Ad2. I'd rather prefer if they reduced this gap by increasing performance of low end cards instead of putting leash on development of high end ;) And actually next generation of cpus is doing exactly this. By greatly increasing power of integrated GPUs they give stable base for delevepor to benchmark against and also this will make tons of low end cards pointless which mean GPU manufacturers will have to impove low end gpus to the point when they bring serious performance.
