I'm thinking about selling my powermac g5, and I'm wondering how it would compare to a new, 17'' mbp. It's for extensive photoshop work, and video work. Here's the comparison Current g5, quad core, 2.5ghz, 16 gb ram, dual 500 gb drives ( the apple ones) theoretical mbp: 2.9ghz, 8 gig ram, 256 ssd. I would think the new intel chips on the mbp would help a lot, but would a new dually beat an old quad? Obviously, a new mac pro would beat the mbp, but I'm hoping to get rid of a big clonky desktop ( and just have my mba, and mbp).
