I hve a power mac g3 right now and want to get a new comp since this is a few years old. I want to get one that works great at making recorded dvd's and such. i mainly use the comp for mkaing cd's/media/mp3's etc, and want to get a good one that can burn dvds well. im also looking for the most affordable since im not rich. would a new imac g5 be good for this? looks like a good deal.
