Hello, I want to buy the mac mini 2012 (i7 3720qm + fusion drive + 8GB ram) and i have few question before i do that. Currently im using an old pc (i7 920 on x58 motherboard's chipset + 3gb ram + intel ssd + hd5450). Is the performance improvement will be significant between my old pc to the new mac mini? how much improvement will be a percentage? 50%? When the 2013 mac mini should be out? What else I need to know before moving to mac?
