I'm completely new to the forum and completely new to mac's as well. For the last few years I have been fed up with pc's in general, and have decided to go with mac's. For my first machine, I chose an early 2005 powermac g5 dual 2.0 ghz machine. I realize this is not the best or the fastest to start out with, but I don't need the best or the fastest. Yet. What I needed was an inexpensive solution to get me up and running on a mac. My intent is to use this as a learning process and if I screw it up, well chalk it up to experience. What I plan on doing is first maxing out the ram to 4 gigs. I also want to add a 1Tb drive for internal storage and swap the main drive for a western digital 300 gig 10,000 rpm velociraptor drive, and then add a geforce 6800 ultra. To top it off, I want to add a Blu Ray drive. According to my research the 10,000 rpm 'raptor drive should help with system speed and the added ram and better graphix card should help too. My main question is what about drivers? Most everything i've seen for info so far has not said anything about drivers or software at all. It's as if everything is "plug and play". The research i've done for the 6800 ultra has said nothing about required driver's. same with pci usb cards. Plug and play? I heard someone say that driver's we're built in in a mac. Is that true? The blu ray drive I looked at said it was compatible with the mac pro the g5 and the g4, and was plug and play. How is that possible? I am taking a photography course and need to run photoshop cs4 "adequately". I plan on running dual monitors, hence the 6800 ultra for a better video experience. At some point down the road, I will upgrade most likely to a mac pro, at which point I can part the g5 out and get some money back.
