17" or 20" iMac?
If you're looking a the 17" I would buy the new Core Duo model as the price is just that good for what you get, not matter what a discounted model would be. The 20" could be a different story depending on you budget. If it was me, I wouldn't buy anything but the newest model Intel iMac as I know I would just wish I had the new one a week after I purchased the G5. But that's just me!
