Buying new VGA to play CoD

[zanzark]

I agree with you NedLynch, I don't intend to buy a very expensive card, as my 6850 runs the game ok.
It seems that the GPU is enough, but the VRAM is insuficient, as I can see in GPU-Z where it shows the VRAM Full, and another 800MB of "dynamical memory" allocated.

I think for those that can't afford a really expensive card, a 560,570,68xx,6950 with 2GB is ok.
