My concerns with sticking with a G3 upgrade (OWC, 333 Mercury with 1 MB L2 cache) was 1. heat; 2. power supply - the beige is only 150 watts; 3. overclocking was easy (now at 400 MHz, bus speed original); 4. cost - only 25% of a G4; 5. G4 native apps are few and I don't use them (OS X is optimized for G4, but I suspect only really true in 2003). Cheers George
