Hi all! I've prioritised a bit and decided to sell my 2010 MBP and buy a new iMac. A few questions! -This MBP is a 2.6ghz i7 (dual core). I'd like the base 21" iMac with the quad core i5. Is there a performance increase here from my MBP? -I've noticed the GPU is the same as t he ones they put in the notebooks at the moment. How does this fare for light gaming (World of Warcraft, TF2 etc)? -I'll be using this mainly for music editing (orchestral, so HDD intensive). Is this a good choice? Offtopic, but I'm selling my current MBP and I've advertised it as including student warranty (UK educational purchases include 3 years as standard). Is this still valid with the next owner? Do Apple still offer this warranty plan with 2012 purchases? I hope people can give me some insight Thanks!
