The price hike in the UK kind of caught me by surprise. I ended up shelling out more than £2900 for a 15/2.7/1Tb with the student discount and apple care. I am a bit unsure whether I should have taken the 2.9 and upgraded to the 460. Can any of you guys explain a bit more in detail if and when I might regret not having that amount of extra power?
Forget the 2.7 -> 2.9 CPU, the biggest difference that will make is in your wallet. But I think you should have gotten the 460 upgrade. It's the least expensive and the most worth it upgrade in my opinion.
