In a little dilemma. I have a lot of these as I am a Apple consultant and do onsite work. Here is the situation... got a dude who uses Adobe CS4 ALOT, and uses Final Cut Studio every so often. He wants to have these machines for a decent amount of time. He is wanting me to choose for him between two options for his needs, he says he needs something portable. (it dont have to be the best portable machine though, he says) 1. Get a 09 2.26Ghz Mac Pro 8 core and also get a 2.4ghz uMacBook. or 2. Get a 09 2.66Ghz Quad MAc Pro with the 2.66ghz uMacBook Pro. I was reading somewhere that the 2.66Ghz quad runs some programs faster or something becasue of the higher clock speed if your not using all 8 cores? IDK but any help is much appreciated!! Oh yea, either way he will have the ATI 4870 card in the MP.
