Hi all. I just bought a G4 Quicksilver with cinema display for $10 off Craigslist. It has the 800MHz dual processor, 1.12GB RAM, CDRW drive, and a 40GB HD. I would like to max this computer out, or get as close as possible. So far, I have added an 80GB HD to it, bought an Airport card, a 512MB RAM stick to max it out to 1.5GB, and a Pioneer DVR-108AA DVDRW from a G5. Now I'm stuck on the graphics card and CPU. As far as the graphics card goes, I'm stuck between a Radeon 9800 Pro or a Nvidia GeForce 6800GT. I have read that the 6800GT is a much better bang for the buck if I flash it myself, and the 9800 Pro is more expensive and not as powerful, but very easy to get working on a Mac. Which do you recommend? For the CPU - I have found a dual 1GHz processor from another Quicksilver for $99 on eBay, is it worth paying that much in terms of performance gain and resell value? If not, are there other upgrades that would be better for the money or should I just leave it? I'm sure I'll have more questions later, but this is it for now. Help is much appreciated.
