Oh, CoD4 will barely run with minimum graphics settings with HD2400. 
Omfg, what are you talking about? HD2400 is equal to smthing like GeForce 8400M. My friend has a laptop with 8400M + AMD Turion 64 x2 tl-58 (1.9GHz) and he runs cod 800x600 on 50 fps. And this computer has Core 2 duo and thats way better than AMD Turion tl-58. And desktop graphic cards are much better than the laptop cards. My another friend has a 7600GS and he runs cod4 @ 800x600 @ 90 fps
7600GS is faster than HD2400.
Can HD2400 really run CoD4? Anyway, even if ti can, there is no hope of seeing good graphics at any game, and IMO CoD 4 just sucks.
