MAC Upgrading

U need a new Mac, even if you could get a CPU upgrade there wouldn't be much point. They are expensive, and you wouldn't really see the benefit due to your slow BUS speed ect. So yeah, u need a new Mac IMO.

 

if he has a 400 G4 tower then he has a 100 bus. he still could put in a g4 say 1 gig OWC or giga & decent video card say ati 9000 and up your ram but for almost the same price you could get a new emac at 1 gig that would be faster then your old machine that was upgraded and get new panther with it. Time for new Mac but those upgrades could keep you going on that old machine for another year or two. ask yourself how much i want to spend and go from there.

 

what's your budget?
New eMac's around $799 1ghz, 128mb, 40gb, cd-rw,radeon 7500 from the apple store. (refurbs can be good if you can find/trust them G4MDD 1.25dual approx $1300)

If you can afford another g4/g5, definately go that route. If you can't I'd suggest get more RAM, 128 isn't going to cut it.

Radeon 9000 can be found for around $149 (best i've casually seen)
G4/800mhz upgrade $250'ish
1GB RAM $200

You'll probably want at least another drive (or two) for storage and scratch use. on sale IDE drives $100 for a rather large one.

that's about $700 in upgrades right there. The only thing i can say is that if you dont have the $$$ to buy a new Mac, at least you can make incremental upgrades.

hope that helps.
