S!
Good to have the dual BIOS if you pork up the card
I got my 6970HD yesterday and must say I am happy with it and no issues at all
In IL-2, AMD's weak spot, playing The Black Death compared against my previous 580GTX results were very good, and I even used way higher FSAA on my 6970HD
Resolution 1920x1200, Perfect graphics, Stock 4.10m.
Min(580/AMD): 32/26FPS
Avg(580/AMD): 55/53FPS
Max(580/AMD): 70/70FPS
Mind you I used 8xQE + edge detect + supersampling AA on AMD vs 4x FSAA standard(no supersampling) on NV
So the more you slap on FSAA the better AMD shows it's teeth. In RoF I have everything maxed out and still memory usage is only 50% vs nearly 80% on the NV offering
So some headroom there too.
So comparing that for a few more FPS with the 580GTX and a over 120€ higher price tag over the 6970HD..go figure
PhysX is not an argument that sells for me as I do not play shooters where it is mainly used. Also the strange ring you get on water in IL-2 with NV is non-existent with AMD which was a BIG surprise to me. Anyways I can wholeheartedly recommend both 580GTX and 6970HD, both offer a lot of performance in any game
So now seen both sides of the fence and can say both brands have good cards
