anyone running CoD on a System like mine?

[RickRuski]

I'm running a system similar to you but with 6g of ram: -

Asus P5B m/b
E6600 core 2 Duo @ 2.4g
6G Ram
9600Gt 1 gig

I'm getting frame rates of 20--25fps over land, 30--35fps over water with the following settings: -

AA= off
Mod Detail= High
Blds= Medium
Land=med
Forest= Low
Visual Eff= High
Texture= High
Damage= Med
Bld Ammount= low
Shading= low

Grass= off
Shadows= off
Roads= on

Still getting micro stutters, but this should disappear as the game gets more optimised.

It is certainly playable on a low specs system, my advice is go ahead and buy it you won't regret it.
