I currently own a home-built system(thanks to a friend of mine) and am wondering what I should upgrade next. I'm kind of a speed freak and like to keep up in the computer world. The system that I own now is an Athlon 1500 XP, ECS K7S5A, 40gb Seagate Barricuda HD(7200 rpm), 512mb DDR, SoundBlaster Live! 5.1, and a GeForce2 GTS. I am going to replace the GF2 with a Ti4200 right when they come out(already have the money put away), but I am wondering, after I get the geforce4, what should I upgrade? Should I get a new motherboard like an Epox 8kha or Shuttle AK31? Or should I get a faster processor, like an XP 1900 or XP 2000? I need to know what will be holding me back after I get the Geforce4. My system is primarily used for gaming, and I should also state that my Hard Drive is plenty big for me. I am running Windows 2k.
