Hello. First time user of the forum. About a year or two ago, I acquired an older Mac G4 AGP from someone who said it was "broke" and was going to recycle it. Turns out the OS just needed to be re-installed, so she is up and running. I initially installed Leopard, but it didn't run as well as I would've liked, so I put Tiger on it (running much better). After that, I maxed out the memory @ 2GB(4 x 512MB PC133). Then I installed a 7200RPM HD to replace the slower drive. I also installed a DVD R/RW and maxed the processor to a 1.8GHz single core. Right now, I'm looking to bump up the video card. It's my understanding that the 9800 is best card for this system, but I'm not looking to spend that much. I will only be using this system to stream music from Grooveshark and Pandora, so it needs to run Flash content well. Currently, it has the ATI Rage 128 Pro with 16MB VRAM, which is next to nothing. Like I said, I don't need a crazy card, but I'm not sure the difference between one 64MB card and another, or should I go up to 128MB. Also, I'm wondering if there is a Gigabit PCI card available and a good sound card? Suggestions?
