Dear all, I have bought a Macbook Pro 15" and i know there are loads of forums regarding this, but really does it warrant spending an extra £200 on the 2.3GHz are there much real performance gains. You get a better Cache but really does that justify the cost? Would i actually notice anything to be honest, or is it people just want the most expensive Mac? Future Proofing is a load of Garbage as something next year better will be out and i presume its rare to have quad core's on Notebooks. Went for the 500GB 7200rpm hard drive, and the high resolution glossy screen and the Apple Care with the student discount Also what programme would you recommend to start simple video presenations Any thoughts?
