You might want to get a better GPU to handle higher settings

Why's that ? i think Radeon 6870 is more than enough to have it at max settings.... or i'm i missing something here? =s

Ultra includes 2 types of AA one is a post proccess which is Morphological Anti-Aliasing like the AA used in Uncarted 3, Killzone 3 and God of War 3 amoung others which has a small impact on performance. But also differed MSAA which to get a bit technical, BF3 usses a differed renderer which uses a technicel known as multiple render targets which runs 3+ passes on geometry but allows developers to basically use as many light sources as they want, the head graphics programer on BF3 (known as  Repi) has a demo that uses 1000+ dynamic light sources in a single scene for example. The downside to this is that traditional MSAA uses the depth buffer to know where the edges of objects are to aply AA to. But with DX11 you can apply MSAA to each geometry pass esentially running 4xMSAA 3+ times per frame.

Then there are the volumetric smoke, which means instead of using a load of sprites in a pre canned animation, it's calculated in real time in 3D so it can react to other objects in the world, cast shadows etc.

Then there is the ultra high resolution soft shadows and whatever they add to the final version.

TL:DR BF3 basically just throws as much work as possible at the GPU on ultra and you will need at least a GTX 580, SLI if you want 60fps or multi monitor

You may get Beta Ultra tho as that is missing some of the advanced effects
