Hey - I'm going to buy a new 15" macbook pro to use with logic studio. Would I be better off with the 2.3 ghz quad core processor and the 500 gig 7200 rpm HD, or the 2.0 ghz quad core processor and a 250 gig Solid State Drive? What's more important - the internal drive or the processor? Do I need a faster processor than the 2.0 quad-core? Will i notice a difference by upgrading to the 2.2 or the 2.3? (I'm going to upgrade to the 8 gigs of ram) Thanks!
