It's the MAC address of the builtin ethernet regardless wether you use it or not-
No, it really isn't and this statement shows a lack of understanding... Haiku has 32-bit and 64-bit versions, MorphOS does not. MorphOS is 32-bit only.
Yes, you can, in may cases, run 32-bit OS on a 64-bit processor: but it means you're not going to use half the registers in there 64-bit processor. You're using the wattage to run that G5 but it's not going to take advantage of entirely of the 64-bit processor.
Repeating nonsense does not make it less nonsense....
Actual single core performance on MorphOS is about the same as under 64 Linux/BSD/OSX etc....
Why? Because unless that test allocates more than 2GB the upper 32bit of the address registers will be 0 anyways.
In 32Bit mode they are ignored on a 64Bit "modern" OS they will be mapped to a non virtual (physical) 64Bit address (where depending on the amount of RAM installed the upper 29 to 32bits will again be 0.
No effect on handling 64Bit data, no affect on handling 128Bit data (Altivec) no effect on anything happening in cache.
Who said the single core performance wasn’t similar on MorphOS as it was compared to Linux? I never made any comparison along those lines. You’re arguing points nobody made: who are you trying to debate?
I am stating the fact that MorphOS is a 32-bit OS and using a 64-bit proc on a 32-bit OS is overkill.
I am sorry that fact hurts your feelings.
Next talking about “more than 2GB” is pointless as MorphOS can’t use more than 2GB RAM (less in fact).
Only if you fail to understand what "64bit" means in this context...
If MorphOS would for some reason be limited to handling 32 bits of data at a time you might have had a point, but thats just not how it works (and hasn't really been since the 90s).
So having a 2nd CPU/core is overkill for MorphOS.
Having more than 2GB is overkill for MorphOS.
The CPU being able to address >4GB or not is irrelevant.

So it must be even more of a waste to use an AmigaOne X5000 for MorphOS. 64-bit, dual cpu, as an Amiga-like OS, nothing currently programmed to work like the AmigaOS will ever be able to take advantage of either of those features.
If it's overkill, then that's a good thing. Why do you care if MorphOS is a 32-bit. single core, single thread OS? It mostly cares about fast single thread performance and that's what the fastest G5 cpus bring. Sure, it means the most optimal build would be a 2.7 Ghz G5, but considering what it costs to buy bespoke PPC Amiga hardware, any PMG5 is a very easy way to get a near top of the line experience with an Amiga-like OS.
And you talk about it like this is somehow a bad thing.
Could anyone please clarify what does "no W3D" for GFX card means?
Also, I want to use an compatable AGP card with PC bios in my PowerMac G4 QC. Is it enought just to disable 3 & 11, or must it also be flashed with Mac bios?

It was a 3d API used by AmigaOS and AmigaOS-likes, and without support for it, those graphics cards don't have full (legacy) 3d support. As I understand it, no one has written W3D drivers for anything newer than a Radeon 9200.
Depends.
R100-300 needs a flash matching the HW (read PPC OF)
R400 has AtomBIOS, but may not work
R500 and up, have "working" AtomBIOS and should work but your mileage may vary.
I do have a HD3450 that works just fine in the G5, but was a total no show in the G4 (with those pins taped).
If FullHD is enough, try to find either an Apple 9000Pro (64MB) or nonPro (I have one with 128MB) as they make the most sense for this class of system.
Thanks a lot for your answer! Its clear now! I already have 9000 Pro Mac and it seems to be the best choice really.
Btw, I looked up through all our Ukrainian "ebay" (called OLX) and found out that AGP Radeon cards with square memory chips are extremely rare. I found only a few offers of these. Maybe will buy and try to flash it just for fun.
