My current system is a G3/300, 6 GB HD, 320 MB RAM, CD-ROM. Play alot of UT 2000 aka GOTY. Have a cable internet connection running through a 10/100 Switch to built-in ethernet port. Am happy with set-up, but would like advice on upgrading processor. Is it better to stick with a G3 chip and suffer no bus speed lose or go G4 and drop the bus to 66 vs. 100 MHz? A little help here, and would a ATi video card Radeon 9200 PCI version work well with upgrading processor?
