Here's my options. 1. Keep my G4 tower now, and buy an iMac in early 2007. 2. Upgrade my G4 tower now, and buy an iMac at the end of 2007/early 2008. What I mean by "upgrade" is, get the 9800 pro video card so that I can stay up to speed with the latest games for a bit longer, and max out the ram, give it a second Superdrive, and another 250GB internal hard drive. With that, I wouldn't need to upgrade until early 2008. Theres always the option of selling the Tower and getting a mac pro... but I don't think I need that much power. A Maxed out iMac is fine for me. What do you think?
