Question about graphic card & about directx

[jf1981]

Hi,

My actual card does support dx 9 only ( Nvidia gtx260), are there improvements in the image quality with newer cards which support dx 11 when plaing CoD ?

As well, some technical questions, what is recommended ammount of ram for the graphic card ? what is benefit from high quantity for that ram ?

And finally, is the graphic card able to make the game playable with a high enough number of fps in high res high graphics with a processor as limited as Phonom nowadays that much more powerful proc do exist, I mean is the proc limiting the fps or is it only a matter of graphic card power (after all the Phenom is quite capable anyway) ?

Thanks devs, thanks mates.
