G4 CPU's ..
thanks for all the replies guys. I found a ge force 7800 that I really want, but I doubt I am going to be willing to spend $300 for a video card, so I may go with a 6200 for $100. Also, I was trying to find a sonnet but it seems the company doesn't sell processors anymore, and it is slim pickings on ebay. Does anyone know if there is a major difference between a dual 1.6 and a single 2.0, it's only an $80 price difference, so it seems it would be worth it to me to spring for a dual processor if it makes that much of a difference in speed. I am not quite sure I know how to test the wattage of my power supply and that seems to be a big factor on the system requirements for a graphics card. Can anyone point me to a spec sheet where I can find that out. I spent all night last night researching it and just couldn't find what I am looking for. I am willing to replace the power supply if I have to to accommodate a better card, but I don't want to replace it if I don't need to.
Once again thanks for all the help. This is my first project like this, and while I am certainly enjoying everything, there is a lot I need to learn
Cheers,
Andy
I wish you much fun for your G4 project! I am with you on this one, since my "Tim Taylor G4" was a blast to tune up. Its a real design classic that is timeless like a Luigi Colani chair or a Bang & Olufsen Stereo or even an old Porsche 911 ...
1# CPU upgrade:
As far as I have researched in the past there are about 4 different G4 chips around:
G4 7447, G4 7448, G4 7455 and a forth one I can't remember.
Most of the upgrade cards use the G4 7447. In my opinion not such a good choice since it has no L3 cache, however it would be cheap and still a good value.
The G4 7455 was the CPU that had a huge L3 cache and was the fastest one available since the about last year. This baby runs hotter then the other ones but is very fast! If you can still get one, I would go for it.
The G4 7448 is the newest edition to the G4 chips and I have heard a lot of good stories about it. It would be a great choice but it would be the most expensive one as well. This one has not the old time L3 cache but a big part of the chip has been redesigned.

Regarding the Graphic Card, I still have my old ATI Radeon 9600 256MB
Mac Edition here. (This card is the G4 version, there has been a G5 BTO version as well!) I bought it at OWC back in the day ($249) and it got replaced by the Nvidia 7800 from MacStreet. If you want it and if you don't mind the additional shipping from Bavaria - I can make you an offer for 120 bucks. Otherwise I keep it as a spare.
Regarding the power requirements of you PSU, I think you don't have to worry about it. All the G4 upgrades have been sold in the past without a new power supply. You will not reach the limit unless you have both DVD/CD drive slots filled AND more all 4 Hard Drives on your internal power hooked up.
Good luck with your Project !!
