I'm going to send the 7990 back and get a single GTX 770 4gb for much less.
There are some articles around discussing and testing consumer grade cards on CAD programs. It seems that the Titan would be the best. Not the GTX 780ti but the GTX Titan. Thats $1000 and tests faster than even the highest end "professional" card at about $5000! Apparently it may not be as precise in rendering as the other cards but, I don't need that kind of precision. So it seems the sweet spot here would be the GTX 770 4GB. I found one on NE for $369 after rebate. So, the reason I come to the gtx 770 is that it is using the same GPU as the GTX 680, which came in not to too far below the Titan in one of the tests I saw. I opted away from the new GTX 780 and GTX 780ti because another test claimed that the the titan and the gtx 680 performed better in the CAD application.
In the end, the GTX 770 is an improved upon GTX 680 and I figure I'll go for the 4gb version to future proof it a bit and it really isn't that much more. I think the best price I could find on the 2GB version is $329.
So, my impatience in jumping on the beastly 7990 nearly cost me $200 I did not need to spend on a card that, was an amazing deal as a gaming card, didn't fulfill my essential needs for 3D modelling as well as the lesser expensive card.
Thanks for all the comments and advise! I'll return the 7990 to newegg and wait for the refund and see how we're doing on prices then. Of course, I'll be very close to black Friday at that point and may wait and see what prices that would bring.
If you are thinking of cross-firing 2 7970s maybe this would be a better option for you too.
I see NewEgg is out of stock on the $579 right now, but, I have one the way to my house that i plan to refuse shipping on to go back to them.
Maybe you could snag it. I think there is still a $599 one available at Newegg though.
