I don't remember the model(s) exactly and don't have it at hand now (out of my place ATM) but I've got both the "regular" and the "powerful" nVidia GFX boards for the Quad.

any use ?? not tried it as it wont fit in ANY case I have lol so ive never powered it up.

ATI 5970 (dual gpu) 2x 1gb (2gb total) its an absolute monster i think it needs the end handle cutting off to fit in a mac (a handle for a Dell XPS system) and a tdp of 294 watts

I know this was used in a Xeon mac(no boot screen and monster PSU in the macs) in single GPU mode in OSX but dual GPU in windows bootcamp. not sure if it would even boot in a G5.


the 2nd photo I dug it out this week as I was building a new desk for my amiga to fit on :) on the 1084S is Sword of Sodan loading :) just fitted a new power switch.
still messy but at least I can have 2 or 3 systems up now not 1 on the kitchen table :D

Don’t think that card will work in the G5 macs from what I’ve read @Sardine , Nice desk setup I’ve got to design something similar for my man cave lol

@silverdr sound like you might have the 7800GT 256mb (I currently have this model) and the Quatro FX4500 512mb which were originally produced for the G5. I might be interested in your FX4500 512mb if you do have this model.

but would really like a 7800GTX 512mb, that the bios has been flashed so it will work in the last of the G5 PowerMacs

This is the "powerful" one. The "Mac edition". Highly rare stuff.
