I've been happy, up till recently, with the performance of my G4. Until lately, that is, when I've discovered online FPS games. Now, I'm starting to wonder... Is it possible, or feasible, or even reasonable to upgrade to a faster processor? What I have: A Power PC G4 with a 733mhz processor, 1.5G SDRAM, ATI Rage 32 mb video card. I can't find a build date right now, and I know the video card isn't the strong point of my system but... The game I'm currently into, I've been told by all the "gurus" is more processor intensive, than games such as UT2k4, which requires an awesome video card. Thanks for any help!
