I just recently purchased my new toy, a Power Mac G5... I'm curious about upgrading, I'm more than capable of doing it, but I'm used to the PC terms and hardware specs... so getting the right hardware that is compatible with the Power Mac is new to me. I have: 1.8ghz single 2.5gb of RAM (2 x 1GB, 2 x 256MB) 160gb HD no airport / bluetooth installed 10.5 I have limited money right now so what do you all think would be the first area I should upgrade? I would like to have a bigger, faster hard drive but I'm concerned about getting the right speeds. Most of the SATA drives on newegg are all 3gbps and I see the PM specs at 150mbps.... thoughts? I'd also like more ram, my hope is that might improve the speed of the machine a little (which would be nice). But I'm not sure about brands for memory, I know that I need PC3200 though... thoughts? For Airport, I need to get an Airport Extreme card right? How do I get bluetooth in too? So basically, I'm looking for tips on upgrading this nice computer, which would help more? What should I get? Is there something better than newegg? Thanks everyone!
