Hey there, I'm trying to get a second graphics card (nvidia geforce 7300 GT) to run an HDTV as a third monitor for final cut pro. My mac is a quad core power PC G5 with nvidia geforce 6600 (not the new intel one).

When i fitted the card and turned the mac on not a thing happened, the only difference was in the system profiler in the PCI cards section where it called it a PCI0, 400 VGA compatible controller (not nvidia geforce 7300 gt which i thought was strange)

Iv tried everything i can think of including putting my main mac monitors into the new card to see if it would run them which it didn't, which makes me think its not installed properly or isn't compatible with my mac. When i turned it on i expected it to say "found new hardware" or something similar but i got nothing.( i also ran software update)

Anyway i'm stumped so if anyone has any ideas that would be great.

BTW i asked the guy in the apple shop if i could use a second graphics card to run a third monitor and he said i could. he also said it has its own drivers and is just plug and play.

Forgive my ignorance, but could this be a PCI-E vs. PCI-X issue?

Hey Shaun, i think as far as i know the card is PCI-E and so is my mac......at least it said PCI-E on the slots when i had it open.

Andy,

Here is your answer:

The 7300 GT only works on a MacPro; the EFI firmware won't talk to a G5. I have no idea if you can still order cards for a G5 through Apple but I'm sure there are resellers out there that can.

Hi Robert, thanks a lot for finding that, i figured as much. I can print that and take it to the shop i bought it from and get my money back.

much appreciated.

Andy.
