I've just treated myself... again... 30th birthday coming up for a pair of these.
Palit 1280MB GeForce GTX 570 Sonic Platinum NVIDIA Graphics Card
ATI drivers and Crossfire just got too much to bare, and for when multi gpu didnt work I needed something beefier.
So now I have a pair of few month old 6870s for sale if anyone in the UK wants them. lol
