Yesterday, Gamestop revealed the minimum system requirements for Call of Duty: Modern Warfare 2. Today, Infinity Ward sent out a list of minimum specs that differs from Gamestop's listing in a few key ways.

• OS: Microsoft Windows XP, Windows Vista and Windows 7 (Windows 95/98/ME/2000 are unsupported)
• Processor: Intel Pentium 4 3.2 GHz or AMD Athlon 64 3200+ processor or better supported
• Memory: 1 GB RAM
• Graphics: 256 MB NVIDIA GeForce 6600GT or better or ATI Radeon 1600XT or better
• DirectX: Microsoft DirectX(R) 9.0c
• Hard Drive: 12GB of free hard drive space
• Sound: 100% DirectX 9.0c compatible sound card
• Internet: Broadband connection required for Multiplayer Connectivity. Internet Connection required for activation

The differences between the two sets of specs lay in the hard drive space (IW says you need 12 GB, instead of 16) and the processor (3.2 GHZ, not 3 GHZ). Also, Gamestop made no mention of online activation.
