I don't understand the people buying brand new 7970's thinking the resell value will be better, it's going to lose a few hundred $ in value the first few months, while a 5970 still maintains the majority if not all of it's value if you bought one when the 7970 came out.  Anyway more for me I guess.

Very simplistic view.  Most 5970's are 2 years old, and many have been overclocked the entire time.  It is a gamble paying $400 for a card that could go bad at any moment, thus taking the re-sale value to nearly zero. 

Many people would rather take a garaunteed 150-200 dollar hit on a new 7970 that will very rarely crap out (and has a warranty even if it does), over a very sketchy 5970 that could cost you 100% of your investment. 

I have about a 50/50 split in my farm on 5970/7970.....so I have thought this through extensively.

For my watercooled servers I am buying 1 more 5970 (and maybe buy a hot spare) and then I likely will only consider new 7970s or 7990s going forward.  The bad news is for watercooling only dual GPU make any sense so I will need to wait.

My pump and radiator has enough capacity for 2 more rigs of 5970s but honestly their age is starting to concern me.  Now if the price drops to sub $300 that concern will go out the window. Smiley

You can already buy them in Portugal: http://pcdiga.com/pcdiga/Produto.asp?Familia=&Artigo=9711 .
For anyone wondering the cards sold out in like half an hour!

549 Euros for a card w/ retail price of $500?  Ouch.  Guess some people had to have it.

I hope AMD counters with a drop in 7970 prices.  If they do, I just might go with some 7970s instead of waiting for the 7990.

499 Euro in Germany, including tax:

Still not cheap

Agreed.  Lets go pricing war! Lets go!

This is gonna be fun, since nVidia has got huge margins on this GPU. This was supposed to be the "performance/$" oriented card, like the GTX 560 Ti and GTX 570 were. I'm expecting heavy price drops on this one as soon as supply stabilizes.

Newegg listed "Shader clock: 2012MHz".

Interesting... 1536 ALUs at 2012MHz would give it more processing power than a HD 6990. Either the GTX 680 is going to be the fastest GPU for mining, or it is a blatant mistake from Newegg or the microarchitecture has undisclosed limitations that would prevent exploiting all this apparent power.

Per the NDA lifted today, this was a blatant error. The ALUs will run at 1006-1058 MHz, which should allow this card to mine at an upper bound of 450-470 Mh/s (80-85% the speed of a HD 7970.) This is assuming of course thar Nvidia added a BFI_INT-like instruction to the architecture, which is not certain. If not, performance would be much lower...

Edit: for more accurate perf estimations see https://bitcointalk.org/index.php?topic=73627.0

WOW. This would be heaven if true.

Can you say 14 GPU Nvidia mining rig with a relatively cheap motherboard ?

The only thing that may kill it is the crap MH/$ value but prices will drop anyway ...
