It's pretty early to be asking for reviews ;)!

Seriously though, didn't Anand or someone else underclock the 5800 Ultra to 5800 speeds and benchmark it (I think it was Anand). That should give you a very good indication of how it will perform...

My guess is to overclock a 5800, you would need their ridiculous fan.

With the stock fan (one slot?) I bet (pure speculation) that you could get one up to maybe 450mhz or so. Theres not much overhead on the FXs from the look of it.

Nah, Gainward has that 7db setup that we will have to see to believe. I think that if I spent some money on cooling (not gonna be anywhere near 100$), I could get it up to 500/500. Difference between 5800 U and 5800 = 5800 has a simple cooling solution and is an underclocked version of the U version? Nothing else, right (eg, RAM, architecture)?

We still don't know that yet. And I'm 99% sure there will be a fundamental difference between the two. The 5800 (non ultra) has only 400 MHz DDR memory, so it might have BGA DDR 1 or cheaper DDR-II; I highly doubt they'd put the same expensive (rare) 500 MHz DDR-II memory in a slower card.

But the cooling system is going to cost quite a bit, it might be they put the speed binned cores on the 5800, and cut costs with the lack of vacuum cleaner, which would give cheaper costs, then use the same RAM, because the cost of the cooler must add quite a bit to the card and could be a significant amount of the price difference.

That sounds like wishful thinking to me... Also, if they don't put a vacuum cleaner on the 5800, doesn't that imply that they're probably not speed binning cores (ie all chips can probably run ~500Mhz with a vacuum cleaner, and therefore ~400 MHz with only a regular fan..? If they were speed binning then that means they have fast cores in the high end product and lower cores on the low end product (eg. you need the same cooling to run at a lower speed) )
