unfortunately, video cards with Mac firmware are incredibly expensive compared to a PC card. I only have this one card and I'm reluctant to throw more money at this machine.

I sold my dual core Opteron box with four 400GB drives and 2GB of ram for less than what I have into the G5 at this point. I'm going to have to cut my losses soon. Not to mention the ridiculous amount of time I've spent on it the past couple weeks.
