Excellent thanks a lot for the effort Tom !
So it was as I thought then. The 6970 does indeed sit between the 470 and 570 and the 570 is now the card to have.
What's a shame is that any one sitting on the side of the bed deciding which woman to spend the night with has now been thrust into the arms of the green bitch. It's going to be a good Christmas for Nvidia... I mean, if you weren't sure before then for £20 less at least then you can be sure now.
Ah well. Good luck to Nvidia. This should keep them from going bankrupt and keep prices fair for us gamers which is, after all, the most important part
Again, thanks for all your effort and hard work. Truly appreciated here
