I think the high end G5's will outperform the X1000 in many (most?) benchmarks.
Yes, in the Power consumption at most.
In noise generation as well.
In dust collection benchmarks if you don't clean it often.
I see a lot of old mac
scrap loving guys. You assume that the old cheap machine is good for you, but for me a new less power consuming machine like AmigaOne X1000 and Sam460 are better purchases, even if more expensive than an old G5 Mac.
In two years of usage time, I will pay less for my new AmigaOne hardware, than you for your old Mac, if I calculate the electricity bills in the equations. And I do.
If someone else pays your electricity bills, then buying old power un-efficient Macs with CRT is good. Too bad I have to pay my bills by myself, so I can not afford to have old G5 Mac or CRT machine. Will go for the AmigaOne though.
Of course my equations will not work for you because:
1. You don't use your MorphOS machine a lot.
2. You don't pay your bills.
3. You hate having new stuff.
4. You want to look cool by showing your friends how your old Mac runs another operating system (how unimpressive).
I believe people will be more impressed to see MorphOS running on NEW Apple or other brands hardware, but that is just me.
