here's the first CF review of the above mentioned cards if you're interested...I found it quite interesting...
I'm torn between 2x6870 and 2x6950 atm...what are your opinions?
also, looking at the temperature figures in the review, I was thinking of watercooling them if I go down the 6950 route, but i wonder how much would that cost using decent components?
