nice. im going to be getting two of them when they arrive. dunc might give me a deal because i doubt that they will be cheap.

[DreamingSheep]

Yeah, will be interesting. I saw a price guess a while ago but I can't remember how much it was, but it was lower than I expected. time will tell.

I also doubt there'll be any need for two of them really.

The big problem is you will need the Ivy Bridge processor to use it at PCI-e 3.0 but I doubt it will top out Sandy Bridge until 3 or 4 way Crossfire

Lowest price I have seen is £420 but also up to £530 which puts it quite some way above a GTX 580. My guess would be for the 7950 to come in at around £375 - which is still expensive. As for going CF, single cards perform well even at 2560x1600 as shown below for BF3 at Ultra. Your resolution would need to be a little on the high side to justify more than one!
