I'm waiting for my PM 2.7 for home to ship and I'm trying to determine the best way to spend my money. I use FC Studio and transfer a lot of video files back and forth to external FW800 drives. Would it be more beneficial to purchase a G-SATA 500gb external drive or would I see a better benefit for what I am doing by expanding my 4gb RAM to 8gb. I do tend to use FCP and Motion as well as LiveType simultaneously. Any PM's out there with 8gb, I'c love to hear your experience with this. Thanks.
