Well I have a laptop with a i5 3210m and a hd 4000 graphics, I can run bf3 multiplayer 64 man smoothly on low, as long as I'm not playing dense maps, but games like shogun 2, I can max out easy. CS Go, lol, tf2, garrys mod, no sweat. So if you get a i5 xxxx , with a hd 4600 instead, you should be able to run mw2 smoothly, cause with mine I can barely get it over 30
