Hi all, Noob here, hope I've posted in the right area. I'm looking to buy a MacBook Pro 15" and had a couple of questions; If I buy the 2.4Ghz model today, does it have the new Penryn chipset - and if so, what speed is the FSB ? Is it worth me buying now, or other than the Rumour Guides hinting at a redesign of the case, does anyone know anything more about a refresh (either at WWDC or otherwise) ? Finally.... Is it worth upgrading to the 7,200rpm disk? Has anyone who has got the upgrade noticed a huge gain in performance ? Thanks for your help.
