x8 vs x16 should make no difference.

Now the make sure (before you buy 14 other cards):
- did you check the card in a PC
- if not, does the G5 have a working OSX install, if yes boot with both NVidia and Radeon installed and check if the radeon is showing in system information
- what kind of screen did you use, very high and very low resolutions can cause issues
- when booting does the G5 ramp up the fans after time and does the caps lock LED still work will tell wether MorphOS has crashed or is still running

Yeah, I've got a 11,2 with Mac OSX 10.5. Will check the card there.

I've put the HD card into that G5 with Mac OSX installed. When going to System Information and PCI cards it reports an error saying that "An error happened while collecting information" (or so). Maybe that card is really broken. :(

On MorphOS I see that it is booting. My USB hub is starting the blue lights and I can reset via the keyboard. So I guess it doesn't crash but there is just nothing on the gfx card output.

Getting the X card later today....

I just found an Asus EAX 1600 PRO from an old PC lying here. That's not supported by any chance, or?

Oh, surprise. This thing actually works. Seems it's Radeon X1600 Pro based. :D
It's bloody noisy but quite fast.
AirPort works, too.

But that's cool.
I just found that the other 11,2 I have is actually a 2,3 GHz version. So I'll have to move everything to that one. Suppose it's a bit faster. :D

Pretty much the low end when it comes to plausible GFX card in that system

Or you "just add" 500MHz to the 2GHz one.

OK, may be. I'm a bit out of this. Since many years I just buy Apple devices and don't care about what is in there GFX related. In Apple Silicon Chips you can't change it anyways.

How? Is that what you mentioned in the beginning "going all in"? I didn't know exactly what you mean.

Take 1 CPU out of a Quad.
Installer AirCooler from 2.9 or 2.3GHz CPU
Drop CPU into single CPU G5 (2.0 or 2.3GHz)

-> 2.5GHz DualCore with 1.25GHz FrontSideBus

OK, for that I'd need a quad first. :|

On the other front:

The X1950 Pro worked fine. Though not long. I chose a high resolution in Unreal then got a colorful screen and that was it. Card doesn't come to life anymore. Maybe I put it in and out also a bit too often. :(

But it worked and it wasn't that noisy. The fan was temp driven it seems.

Now for what I can say I've got a working 11,2. That's great.

Well the good thing is that quads are known to blow their PSU, hence plenty of CPU modules to be found.

Does the type of memory play some role whether the card is supported? Like DDR3 vs. GDDR3?
