ATI cards are not supported and since this seems to be your primary card, it may throw off AE. Perhaps consider getting rid of it, if this is realyl that important to you...
So that means After Effects cant bypass one graphic card, and utilise only the CUDA cores on the other cards?
I tried removing the ATI card - now I've got only the 2 quadro cards installed in the mac.

Still the problem persist. Any ideas?
So you have 3D extruded text and you are in the Ray Trace Mode.
Have you created a light so the object can be seen? Kind of crucial step I didnt see addressed in your posting.
I have created a light yes.
The weird thing is that the composition works in Fast Draft-mode. The falloff from the light is displayed and everything. But once i switch to any other mode, for instance Adaptive Resolution or Final Quality - the object dissapears.
Though I can still see the whole scene and the outlines if I hoover the mouse over the object.
