Thanks for the info, I was hoping someone who had owned one might chime in and give some first hand experience. So would you say, that upgrading from say a G4 500mhz to the 1Ghz wont actually be that much of an upgrade? That the cut you take to the system bus is more detrimental to overall perfomance? At the moment my system does take a while to boot, say compared to my G4 1.55Ghz powerbook, but thats to expected. I don't think I could handle it being slower, thats the opposite of what I was hoping to achieve.
I'd prefer not to buy another system but max out the B/W as best I can. I've just upgraded the video card to a Radeon 7000, in place of the stock Rage 128. Thats made a huge difference to gaming, but I was hoping I might be able to upgrade the CPU. I think the B/W will go up to 700mhz G4, before the bus speed has to be dropped to 66mhz. Where as no such drop exists with the G3, sadly however G3 upgrades are really rare on the ground.
