How well would 10.3 or 10.4 run on a 400mhz G4 with 320mb RAM?

I'm guessing, barely.

actually you'll be surprised. If you turn of the doc resize, genie and text anti-alias it not that bad. I had 10.2 running on a B&W 450 with 320Mb.

Much better than 'barely.' I've had 10.3 and 10.4 running on Beige G3s with 256-352 megs of RAM just fine as a web/emailing machine or a server. It's quite livable, but more RAM will make a huge difference.

Add some more RAM. Mine had 640mb and ran Tiger fine.

10.4 on a 350mhz b&w with minumum ram for tiger is doable. I use it for music serving only though.

I have Panther running on a clamshell iBook 300MHz. It has a 5400RPM 40GB HD and 320MB RAM.

It runs great for surfing the net, email and listening to iTunes. I use it mainly for streaming my iTunes library to my living room. I could use it as an everyday machine if that was all that I needed to do.

Im running 10.4.6 on a 400mhz G4 Sawtooth
1GB RAM
120GB
GeForce 4MX 64MB AGP

It moves right along upgrading the stock AGP Graphics card helped the OS alot, Quartz Extreme speeds up the GUI alot.

Its doable, and it will work great if your comp is sufficiently upgraded.

I would recommend 512 mb of ram, possibly more, and a fast 7200 rpm hard drive.
Also I would highly suggest upgrading the video to something that supports quartz extreme. I used an old PC Radeon 8500 lying around, and I flashed the bios to make it work on a Mac.

It works just like a charm. Probably close to what new macs are like (except when it comes to using demanding applications)

oh yer, os x really feels slow with a clunky, noisy hard drive. 80gb 7200rpm in mine. great. my mac actually felt as fast as the new intel imacs i tried in the apple store.

I've got a powermac G4 400mHz running in the office with 10.4.5. No problems on it. It does have a gig of ram and twin 120gig drives in it.... but the mac keeps a running fine. Easily multitasks itunes, safari and word no problem (although good ole microsoft does keel over all the damn time- no supprise there then!)

i really wish the cpu ugrades for these machines were cheaper though. right now they are way overpriced! you are better off buying a new mac, if cpu speed is of concern.
