I've been reading these forums for years now but never posted. But now I would love some advice! I currently have a trusty (and loud) Power Mac G4 MDD (dual 867 with an original SuperDrive; with a 17" cinema display) that has done me well for the last four years. I've upped it to 1 GB of RAM and added a 180 GB HD. But now with these new iMacs I've been wondering whether I should put any more money into it. Here's my dillemma: I can spend about $1000 and make the MDD really fast and something to get me by for the next three or four years. I would max the RAM to 2GB, add a USB 2.0 PCI card and Pioneer DVR-111D SuperDrive, put in a new graphics card, throw in some quieter fans, and add one of those fancy processor upgrades to make it a dual 1.8 GHz. This computer has done pretty well for me these last few years, and it wasn't until the last few months that it started showing it's age (at least for what I do...and it probably didn't help that I bought a 12" PowerBook 1.5 GHz last summer which is a bit snappier). All I want is something that will get me through until I have to buy an Intel Mac. On the other hand, I could save up $2000 and buy a 20" iMac and be happy (but with a lighter wallet). There are pros and cons to both, but I wanted all of your opinions (if you'd be so kind). I use my computers mainly as multimedia units (encoding/watching a lot of H.264, iTunes/iPod/MP3, using Photoshop and iPhoto for basic editing). I'd also want to eventually do some movie editing (home movies and the like...no big budget pictures) but as of yet don't have anything that needs editing. Wow, didn't mean to take so long to get to the point. So anyway, what do you think?
