Are you happy where you are now? Can you wait? would you rather have a awesome rig right now? All questions you will have to answer yourself, I personally do not see anything on the horizon that a Dual HD69xx setup cant handle.
Pci-e 3.0 complaint card. Will that be the new marketing scheme to sell the newer cards just like dx 11 was with the current and 5xx series? Pci-e 3.0 no speed increase just almost no overhead and reduce latency. Now how will a gpu design make the difference when its the controller and software doing it? If you stuck a older card in there youll suppose to receive the same benefits right?
I noticed they say a increase in the stream processors but on what bus? 256k no thank How your going to feed all those processors on that bandwidth. Gpus is all about bandwidth and the more threads it can run the happier.
My preference is to use a great single card where it will do the job.
Unless you are looking at triple monitor gaming, I do not see the need for dual cards. just my opinion.
A 6970 should be fine.
Perhaps even a GTX580.
Current cards do not slow down with pcie2.0, so I see little prospect of advantage to the upcoming 28nm parts on that score.
If history is a guide, a launch of new high end cards, stronger than any predecessor will be acompanied by very high prices.
From what we think we know about the 7 series so far, there won't be a performance increase until you get the highest cards. The 78xx are identical to the 69xx cards, but with power numbers. If the 79xx cards are out of your budget, just get the 69xx cards now.

Huh? I think I know what you meant, and if you did your wrong there too.
