I referred to the 2.0 GHz 7447A upgrades, not to the 2.0 GHz 7448 ones.

> The 2.0GHz CPU I was referring to is the G5

I know, but that is not what my question is aiming at.

No, I do not see any difference in cost efficiency between the 1.6, 1.8, or 2.0GHz G4 upgrade CPU's.

I guess it really depends on how cheaply you can find the 1.25GHz & 1.42GHz G4 PowerMacs, compared to the cost of buying an older, slower G4 PowerMac & 1.4GHz G4 CPU upgrade. I have been fortunate to have found MDD G4's at very low prices.

Thanks for clarification.

No, I'd probably go with the MDD TOO. The MDD offers a slightly improved drive controller and a slight edge in performance (at comparable CPU speeds).
Besides, you're right, MDDs can be had at a minimal premium over older Powermacs.

G4 Powermacs will provide expansion slots, but for faster CPUs we're going to have to wait for G5s.

Last night I read a post by Fab on another site that stated he had asked bigfoot to test running a 1080p HD movie file using MPlayer on his 2.7GHz G5 running MorphOS. Fab stated that it ran the HD movie with no problems, or was it with no lack of speed and power?

That is very encouraging to know that bigfoot already has MorphOS2.? running stable enough on any G5 to be able to run MPlayer and test a 1080p movie file on it.

Perhaps we will see a public release of MorphOS2.x on the G5 PowerMacs sooner than I had imagined or even hoped for!

Yes, and he stated even some more, albeit not relevant for MorphOS:

"OSX is jut not able to do it because of the additional overhead in the graphic system (or whatever)."

Is it maybe that video replay doesn't benefit from SMP and thus can't leverage the second CPU core to make up for the additional overhead?

Well, some mplayer builds may not be SMP-aware, so i assume that the test is done on a single core. If OSX still doesn't manage to play it properly with 2 or more cores with an adequate ffmpeg/mplayer, there's definitely a big issue with OSX. :)

If bigfoot ever has a free moment when he isn't doing anything more important, maybe he could upload to YouTube a video showing the difference in video quality between MorphOS+MPlayer and MacOSX+MPlayer (or any other HD movie file player)?

He he... MorphOS developers, please stop making more native applications, or we'll never find a reason to buy more powerful computers!

And MorphOS doesn't even have all graphics acceleration functions... Who knows, perhaps GPU driver capabilities becomes more relevant than CPU speed in the future. Wait, it already is!

Bite your tongue jcmarcos! We need all the MorphOS native apps we can get.
