We need to get our hands on one so we can get some output data.   Any mention of price?   I didn't see any in that article.

It probably will have a dvi to hdmi converter like the 5970s. I like that it can be a single slot card! Also, it's a 7990 not 7970 :p

It's not a 7990, either. It's a 7970X2.

Correct, 7990 is trademarked by AMD.

now where are we going to find power supplies with enough 8pin connectors!
If you put 4 of these in a mining rig, you need 12 8pin connectors!

4 cards 2 500W each? Good luck finding a 2000W PSU.

Even undervolted, you're still looking at a 1200W continuous draw...

IIRC 7970s draw about 150W while mining on air, and 100W on water, per GPU.

Yeah, this thing is a stinking power hungry beast.  How soon till we can get a water cooler on one?

Exactly. This is 2 7970s, so it'll be close to 300W per card. He's dreaming of 4 of these, so that'd be 1200W of continuous draw, just for the GPUs.

Two PC Power & Cooling 950w looks to be the best value if two PSUs will work for you.   I use one and it works like a champ.
