Hi, I'm just getting into mac computers. I just picked up a Mac G5 to mess around with for $130 and to do photo editing and getting familiar with the apple experience on the cheap. The model I picked up was the: M9455LL/A Specifics on this link: http://support.apple.com/kb/SP67 So basically I have an AGP slot to work with, not to sure what to use if I went this route. But the other route I was thinking may or may not work is using a PCI-X to PCI-E X4 converter and us a low profile video card instead. Here's the link for that: http://www.buy.com/prod/startech-com-pci-x-to-x4-pci-express-adapter-card-1-x-pci-express-x16/219412770.html What do you guys think?
