Looking for help with graphics card

Hi all and (almost) top of the new year!

I know it's a long shot, but I thought I'd ask here anyway... my Mac Pro (original 1,1) just gave up on me. Booting displays a lot of vertical yellowish lines, the Apple logo appears, then disappears, then nothing. Sometimes the screen does dark blue. I've done the usual PRAM zapping and detaching from mains, then holding the power button, etc. to no avail. The hard disks seem to be healthy, at least they sound normal. I also swapped out RAM bars in groups of two in case one of those is faulty.

So my best guess is that the graphics card has died. I wanted to see if I can test it with a cheap one I buy off ebay. Mine is a Nvidia GeForce 7300GT with two DVI outs. They are quite expensive, while I find several cheaper offers with the same name, but only 1 DVI out, one VGA out, and a S-Video port. Do you know if this card would also work?

Thanks,
Stefan

Stefan -

Check with OWC (Other World Computing, US) for their card offerings, one might work for Model 1,1.

Best, as always.

So I ended up getting an entire Mac Pro, including the graphics card, for less than a card replacement :-)

Once I sold the rest of the Mac for scrap, the card may almost be free!

Cheers,
Stefan
