Curious if you'll be able to run pedestrians over with a decent frame rate? Of course you are! Over at the Games for Windows website, they've posted recommended system requirements for the upcoming PC version of Grand Theft Auto IV. Take a gander and see if you possess a mighty enough rig:

• OS: Windows XP SP2
• Processor: Dual core processor (Intel Pentium D or better)
• RAM: 2GB
• Hard Drive: 18GB free hard disk space
• Video Card: 512MB Direct3D 10 compatible video card or Direct3D 9 card compatible with Shader
• Drive: DVD-ROM dual-layer drive

GTA IV is due on November 18th so you've still got plenty of time to add microchips and what not to your system in preparation.
