My brother called me today and got his hands on a free Intel Pentium 4/ 3.0C GHz 800MHz, Prescott cpu & Verto GeForce 6800 GT Video Card, 8x AGP, 256MB DDR3(actually it cost me a day of carting his bosses kid around D.C. for a day). So, I have decided to throw together a fps machine. Here is what I?m thinking of using so far, suggestions are very welcome. Thanks, be genital.
