"Wat about 6870 vs 560ti?"
6950 2GB > 6950 1GB > 560Ti > 6870
Only overclocked 560Ti gpu's come close to the real-world gaming performance of the 6950 1GB. For unlocking a 6950 2GB check the success rate here http://hardforum.com/poll.php?do=showresults&pollid=7020
. . and never buy a card based on drivers. I've never had major issues with either ATI or nVidia. My GPU's : nVidia TNT2 -> ATI 9500pro -> ATI X800GTO -> nVidia 8800GT (current).
