so i want to retire my g4 cube and get a new imac. the cube has an apple 15" studio display which i'd like to use as a second monitor on my powermac g5, but the monitor requires an adc connection. the idea then is to pull the graphics card from the cube, put it in the powermac. any issues you can think of before i actually pull the card out and attempt this? i think i'd rather buy a new display than pay for a better graphics card for this old display.

thanks in advance.

I believe that this will not work because the video card from your cube is an agp card and your powermac has only one such slot. Depending on the model of G5 you have, the extra slots could be pci, pci-x, or pci-e. check out everymac.com's spec sheets to find out what type of slots you have.

You'd have to use the Rage as your primary video card (you may be able to add a PCI Radeon 9200)... Rage is sooooo old, you wouldn't get Core Image/Video (or even Quartz Extreme?).

I'd go with the $100 adapter to use an ADC ACD with a DVI port, or just buy a new display.

edit: On second thought, you can probably buy a 15" LCD for less than $100. Or sell it, add $100, and probably buy a 19-20".

ah, well, silly me. the graphics card in my g5 is a 9600xt, which has a dvi and an adc connector. that should drive both displays, correct?

thanks.

Yes, that card should run both displays nicely.

For future reference:

* Rage 128 Pro indeed doesn't support Quartz Extreme
* A Rage 128 Pro board wouldn't work in a G5 anyway. The Rage 128 Pro board is AGP 1X (5.0V) and the G5 has a AGP 4X slot (3.3V). It would not fit physically.

Wait a minute... isn't the PM G5 AGP slot an 8x Pro AGP slot?

Yes, and the Rage is a 2x card (Cube AGP was 2x), not 1x.

4x will work in any AGP slot, but 2x will not work in 8x without pin taping - which might or might not work.

Not precisely. There are two types of AGP slots - 5V and 3.3V, and they are not compatible. 1x is always 5V. 4x and 8x are always 3.3V. 2x can be either or both. 2x slots are usually compatible with both types of cards, but other slots aren't, and 2x cards don't always work in both types of slots. You can see which slot standard it is by reading the specs closely - a card marked AGP 1x/2x is 5V, a card marked 2x/4x is 3.3V.
