6990's are now available.

"Limit 10 per customer".  Do you think mining had anything to do with that?

Definitely.

Newegg used to have a 1 item only - limit on high end cards like GTX590, Radeon 5970/6990 etc... For ages.

Not many other demographics besides BTC miners who would need 10 at once.

The 5870s limited you to 99 per customer.  I think Vladimir had to create 5 accounts.

6990s are a stupid buy for mining anyway. $729.99 + 8.50 shipping for ~800Mhash/sec? .93 $/Mhash, or 1.08MHash/$.

Even if you manage to cram 4 into a computer somehow (which is as I understand it not really feasible) you're pulling less than 1Mhash/$, and generating $.017/MHash (per day).

If you buy it for a casual mining/gaming machine, it's still a crappy buy as 2x 6970s are cheaper and run better, but I'm not here to argue that I guess.

What's the MHash/J of the 6990?

You're not counting in other costs:

4x6990 = 8 GPUS, you only need one computer if the mobo supports 4 pci-e slots.

8x6970 = 8 GPUS, you need two computers = two motherboards, power supplies, processors, RAM, casing, possible WLAN adapters etc.

It's actually more or less a bargain plus it saves space.

Yep, also 6990 have a better resell value.

I have 3 in one box with maybe room to sqeeze one more... I wouldn't go 4 in a single system... these cards get hot... VERY HOT, im struggling to keep these 3 under 100c

I'd never put 4 6990's on one mobo, that was just an example. Unless you have a massive water cooling loop.

The air cooler on these things sucks, it's loud, small and doesn't do a very good job of cooling the card.
It's as if they wanted to pave the road for other companies to create aftermarket coolers for it (far as I know, they still don't exist).
