I need some advice on an upgrade. I purchased a Quicksilver 800 with the 17" Apple Display in October. I made the following upgrades: upped the RAM to 1.25GB, replaced the CD-RW with a Pioneer AO5 SuperDrive, and replaced the stock 40GB IBM HD with a Western Digital Special Edition 120GB HD. Now that Apple has announced the new PowerMac and 20" LCD would it be wise to upgrade. I will mainly be using my computer for photo editing, database, and music. What are the advantages of the newer PowerMacs over the Quicksilver, and the new 20" LCD over the 17". I know that there will always be something better available but at what point do you decide to stop. I figure that since my system is still under warranty I would be able to sell it for more than if I waited. What do you think. Thanks
