    Hey guys,

    Been running Morph on my MacMini for a while now, and acquired a Powermac 7,3 dual G5. The only downside is it has a Geforce video card so Morph won't load. I have a spare Radeon HD 5770, but I don't see that listed as supported, nor can I find if that actually even works in a G5 with the Pci-e power connection.

    So my questions are as follows:

    - Whats the BEST video card to currently use?
    - Does the video card have to be a Mac edition? (I will not be loading OS X, just Morph)
    - Any chance the video card could support a res of 3440x1440?

    Thank you in advance!

    1. The best (fastest working) gfx card on AGP G5 PowerMac is currently Radeon X800XT (X850XT).
    2. If you're going to use only MorphOS - it doesn't. But if you wish to finetune something in Open Firmware - do that before you switch the gfx card to a PC one.
    3. No idea with ultrawide, sadly (I'd rather say it's a "no"). It does run at 1920x1200 with no problem, but that ultrawide res has got more than twice as many pixels to draw.

    That's only true for cards with AtomBIOS, i.e. R500-based and later cards. So R400-based cards like the X800XT or X850XT have to be a Mac edition, or a PC edition re-flashed with PPC ROM.

    Cards with duallink DVI (Radeon 9650 for example) can produce 2560x1600@60Hz. Higher resolutions can be achieved by reducing the refresh rate, wether your monitor will work at anything below 60 is something you have to try yourself.

    +1 for the X800XT, but I'd recommend tracking down a legit Mac one. There's nothing worse than compatibility frustration. Just do it right the first time and don't worry about it after that.

    Even when properly tracked, Mac version can be troublesome - as seen in the "X800 (X850?) XT issues" thread...

    What about it? The AGP version is built on an PCIe-AGP bridge and it's transfers are somewhat dissapointing (at least in Linux, and that's what our drivers are based on, AFAIR). So it's still X800XT, sir. I just hope I can get my X850XT to work properly after all...
