Power pc G5 ati video card compatibility

Any ideas on where I can find a ATI X800XT 256 MB AGP video card for a Power PC G5 10.4 OS or where I can buy a compatible one?

This is an old card--im not certain if its sold anymore.

If you just need a n AGP video card for mac try the catalog Macmall:

As you will see, i have narrowed the search terms to AGP video cards and sorted by price. I think the PNY 6200 would be a good choice. ($39) PNY is a good brand.

However we should note that this is still an older model card for an old computer--it will make it work a lot better, but will not allow it to play brand new games, etc.
