Hey all! I have been looking at upgrading my computer, which is a 2010 iMac with a dual core i3 processor. My main candidate is the current top spec 27" iMac. However, I have recently been thinking that I'd love to have the portability of a macbook. Comparing the two, it's surprising how much the closest-priced 15" macbook keeps up with the iMac on paper - a quad core i7, 8 gigs of ram, not to mention a SSD disk (albeit a small one). However, I know that laptop processors often are significantly slower than 'equal' desktop processors, and also that overheating problems and general space issues can prevent laptops from rivalling their desktop counterparts in real-world performance. If I go for the macbook, do you guys think I'll still see a significant performance increase over my 2010 iMac? As I use my computer to produce music, it's quite important to me that whatever I go for next is good with CPU, memory and hard drive punishing applications, and the scale of my productions has increased enough that my current iMac is quite seriously underpowered. I'm guessing that the new iMac would fit the bill pretty perfectly, but I'd really like to be able to work on my projects remotely so if the macbook can handle my work, it might be the better choice. Any advice would be seriously appreciated!
