Yes that card could probably pretty easily play COD4. I think that is one of the new ATI cards. Not really sure what all the bits are for, but as you said the higher the better. I have a lesser card than that and I was able to play the demo of COD4 for good.

Bits = size of the memory bus on the card
not all 128bit are bad like the 2600XT or 7600GT, 8600GT,GTS
256bit+ better cards
