I don't see why not. while I don't own codmw2. I can say my gt230m does play dead space, mass effect 2, wow, sfIV, batman arkham asylum and dragon age at almost max setting at 1366x768.
But I agree with mosox. If the primary use is gaming you can buy laptops with the gtx 260m for the same price you would find most core i7 lappies.
