Hi, I'm a long time PC user and after loving my iBook for the past year and a half I've finally ordered myself a new dual 1.8 G5. I'm trying to prepare for it's arrival and I have a few questions. I've already gotten myself a Dr. Bott ADC to VGA adapter so I can run both my LCD VGA displays. I also have an altec lansing 4.1 speaker system that has a coax S/PDIF input. Can anyone recommend a good way to convert the optical S/PDIF output from the powermac to the coax input on my speakers? I'm also wondering about PC video cards. I seem to remember reading about flashing PC Video card BIOSes to make them work in Macs but can't find the article. Is there anything special needed if I were to decide to replace the GeForce 5200 that comes with the powermac with the GeForce 5600 in one of my PCs?
