i've got a dual 1.8 G5 (4 GB RAM version) w/ an 80GB HD, 1.25GB RAM and 64MB video card. someone is offering me $1500 (i paid $1799 a year ago) for it and they are ready to buy today. this is really tempting. i could grab a new Intel iMac with the money, or even a mini to hold me over for a little while. i also have a 20" Cinema display and i like the idea of keeping it around as it could last me a very long time, but if i get an iMac i'd probably sell it. think i should sell this G5 while it's still worth something or should i just keep it and beef it up a little more and make it last me a few more years?
