As far as what I'm going to do with it...not enough to justify the machine
Mostly photograghy (PhotoShop). The thing is, I've been running an iMac G5 with 1.25G RAM for about a year now, and recently, it's been running pretty slow with multiple images open and with maybe 4-5 other applications open at the same time (Mail, Safari, iTunes, connected to the net with Streaming audio, etc). I'd like to be able to run, additionally, Adobe Lightroom and have Parallels with at least one Windows application running as well, which, of course, I could not do on the PowerPC iMac. You might ask why I need an 8 core megamachine to do even that, or why do I need to have that much open at once. The short answer, on the open applications is...because LOL And why such a hot machne, well primarliy, I'd like this machine to be relevant for a long time to come.
I just wish Leopard was out already.
