Original post: When you're not busy signing internet petitions about Modern Warfare 2, you're likely fretting over your system's innards and whether or not they have the ability to run Infinity Ward's upcoming shooter. Does it have enough gigglebits? Are the processing cores processy enough? When was the last time you fed the CPU's brain squirrel? It's okay -- we're doing the same thing! Thankfully, GameStop has stepped in to reveal the back of the game's packaging, along with the minimum system requirements for the game:

• OS: Windows Vista/XP
• Processor: AMD 64 3200+ or Intel Pentium 4 3.0Ghz or better
• Memory: 16 GB free hard drive space / 512 MB RAM (XP) / 1 GB RAM (Vista)
• Video Card: Shader 3.0 or better 256 MB nVidia Geforce 6600GT / ATI Radeon 1600XT or better

We've contacted Activision for the recommended specs and to confirm that these are indeed the finalized requirements for the game. In the meantime, you can head past the break for the full image (it's a "phenomenon"!).
