I don't get what your point is.... A 6870 is only 20% slower than a 570GTX too, so should we all just buy 6870's or what?
What do you want anybody to say?
A 6970 is a touch faster than a 570, and that is on immature drivers for new tech on the AMD card whereas nvidias drivers will be will developed as Nvidia didn't change much, if anything for their refresh.
Cayman is completely different to AMDs other gpus, and it was only taped out last May, so their driver team should be able to move it along nicely once they get their head around it. Don't ask me how I know, it's just a hunch, but its happened this way for every new chip in the past, so I just don't expect this to be any different.
yea my motherboard has had 10 different bios during the 2 years I owned it.
the same happens with cards, drivers takes time,
its 5 OS to support, a few games, and running everything and writing takes time and a lot of it.
I look forward my new shiny 6950´s
