The easy answer to this query is: How many used Macs are/will be coming on the
market? That's where the numbers will be.

I have a Mac G4-350MHz, and with lenny was able to get 760Mflops from the
BLAS/ATLAS libs via AltiVec. Squeeze appears to run well, though the GAMESS
molecular modeling program has some SIGILL issue (may well be my own oversight
- still testing.)

Also I recently purchased a (used) G5-2.3GHz-2Core. Probably MANY of these
units will be coming on the market as leases expire, etc. An earlier post
appears to be completely correct: Debian on the 64-bit architecture does not
seem to be well supported. The unix-ish part of the machine seems to run
quite well (and FAST!), but high-order features - mainly nouveau - are nowhere
near working, so I have to ssh into it and run exclusively via command line.
Alas, most of these G5 Macs have the GeForce 6600 card, and may be condemned
to inadequate nouveau support -or- purchase of a non-nVidia graphics card.

Cordially,
Dave

Hi Dave,

This worries me. I have a similar machine. Currently it's running
MacOS-X, but I plan to convert it to Debian soon. As with yours, it
has the GeForce 6600 card.

Do you have a recommendation for what video card I should get to
replace it? My video needs are minimal, I just need to be able to run
iceweasel and xterm and a few 2D-gui system administration packages.

Thanks!

Rick
