Got mine yesterday - have to say its an awsome card and despite the negativity by the clear green team fanboys (who seem to cry that its only slightly better but costs more when nvid do allot worse on launches lol) - it's' well worth it.
Pee's on my 2 x 5850's - whilst using less power so I am well happy
3dmark11 score at stock is 7659 - overclocked to stock max 1125/1575 gave me 8919.
Drivers out of the box are early pre-release by the looks of it - It all I used for my preliminary testing (8.9.21.0.0) - Think theres newer ones available somewhere (cat 11.12)
In terms of gaming - I had a quick shot on BF3 (bear in mind this was with a conflicting driver as my previous nvidia card drivers screwed things up AND these are drivers out of the box) - Ultra mode @ 1920x1200 gave me a minimum of 39FPS - average of 50FPS and highs of 80FPS - A good result taking into account these are the first drivers lol.
No crossfire so it was buttery smooth and STRAIGHT away I noticed the difference between the previous nvidia card and this one (in terms of quality) even though I was using exactly the same graphics settings.
I've always said - Nvidia is more about performance whereas ATI are more about quality and can tell the difference between the two cards in all my previous setups.
Well happy

- Alhamdulillah.
