Forgive me if this has been asked before. I am a newbie iMac owner and want to upgrade my RAM. Lots of folks are selling RAM on eBay from their G5 iMacs. Is this the same chip as is used on the Intels?

No. G5 iMacs use either regular DDR RAM or DDR2 RAM at 533 MHZ. You need DDR2 RAM at 667 MHz.

The G5s also used full sized DIMMs, whereas the Intel iMac (and all Apple Intel machines) use laptop sized, 200 pin SODIMMs, so as well as not having the same speed, they are not the same physical size either

You want a couple of these.
