Twin 470's can't handle it on ultra? That's mental.
Surely not that surprising though, GTX470-SLI is over 18 months old and has only 1.25GB VRAM. This is a cutting edge game and I'd imagine anyone who wants high fps at high resolution and has a GPU setup worth under £500 (today's prices) will be struggling on Ultra.
I've got a single GTX470 and if I get this game I'd expect to start at 1680x1050 Medium and then tweak a few settings one way or the other (probably turning shadows down, disabling DOF/Blur, and maybe bumping a couple of other setting up if they don't hit performance too much).
To roll out one of my frequent arguments about Crysis, chances are BF3 on "High" will look better than most games on "Ultra", so just pretend Ultra doesn't exist and the High actually means Ultra
