I am wanting to upgrade either my 17" Unibody MBP or my early 2008 2.8 Octo Mac Pro. I mainly am doing audio production with some video production. My MacBook pro has the stock 320 gb 5400 rpm drive in it and I can see some slight performance loss when using many applications/plugins in Pro Tools. My Mac Pro has the stock 2gb of ram that came in it and I see the same performance loss. So, what do you think I would see the most gain with. Should I go with a 7200 rpm drive (I am thinking about the 500 gig Seagate but I have seen a lot of issues with the drive) or added ram for the Mac Pro? I don't think I could swing adding two 4 gig modules of ram so I would just go with adding 2x2gb sticks from OWC. Thanks!
