From a macforums moderator (in response to my query about 2006 Pro 2x2gz zen 4gRAM) There is no way on this green earth I could ever recommend someone spend what is the equivalent of $1150 U.S. on a 3 year old computer. Don't care what it is or has in it. Save your money. For only another £160 you can get a brand new iMac with a 3.06Ghz Core2Duo. Wait another 2-3 months can probably get it as a refurb for only an extra £60 over the price of that 3 year old machine, and have the full Applecare warranty for 12 months. Take the cash you have, sell the G4 and the monitor and bet you've got almost enough to step up to the 27" and maybe even to the core i5 processor. Betcha, it'll swallow that 2Ghz zeon.
