The Games for Windows Website now offers recommended system requirements for the upcoming PC edition of Grand Theft Auto IV, which seem pretty modest considering the promise of higher-resolution graphics. The specs call for Windows XP SP2, a dual core CPU (Intel Pentium D or better), 2 GB of RAM, 18GB of free hard disk space, a dual-layer DVD drive, and a 512MB Direct3D 10 compatible video card or Direct3D 9 card compatible "with Shader."
