Here's what you need for Call of Duty 4: Modern Warfare;
- CPU: Intel(R) Pentium(R) 4 2.4 GHz or AMD(R) Athlon(TM) 64 2800+ processor or any 1.8Ghz Dual Core Processor or better supported
- RAM: 512MB RAM (768MB for Windows Vista)
- Hard drive: 8GB of free hard drive space
- Video card (generic): NVIDIA(R) Geforce(TM) 6600 or better or ATI(R) Radeon(R) 9800Pro or better
be able to play. Everything's fine except the video card... and that's the most important part. I know from experience that the Intel G41 Chipset lags a lot
on not only high-end games, but 3D games in general.
If you've already bought it, give it a shot. If not, I recommend against purchasing it unless
you buy a new graphics card. I can help you finding a good, cheap one if you'd like.
Hope that helps,
