GTX 580 1.5GB vs 3GB

[Troll2k]

I think I read where Clod uses an abnormal amount of texture memory and that is what causes some of the stutters and micro freezes.Somewhere in the 1.3 gig neighborhood.So people with 3 gig cards are saying it helps in Clod.

However a graphics rewrite is in the works and hopefully some better optimization is in the works.

I have nothing to back this up but if i were buying a new card now it would be at least a 2 gig.But my crystal ball fell off the desk and I am awaiting the new parts.
