[ydl-gen] G5 dual, 2.7 GHz 20" Cinema Display

[Hal Martin]

I don't think Nvidia is interested in supporting PowerPC for 2 major 
reasons.

1) The Linux market is very small compared to the Windows market, and 
most of the Linux market runs either x86 or x86_64 instruction set.

2) Apple has decided that PPC is an arch not worth developing further. I 
think Apple is 100% wrong on this decision, since all modern game 
consoles (PS2, GameCube, Xbox 360, and PS3) run on the PPC arch. If PPC 
is good enough for all those guys, it's good enough for me.

This is why I've chosen my next computer to be an Xbox 360. It has a 
very powerful CPU, (3 core 3.2Ghz), and I can just play games on it till 
someone releases Linux for it. Good luck!
