My 2009 iMac is on its last legs and has served me well. I've decided I'm going to pick up a Mac Mini and a couple of new monitors. The 2.4ghz i5 dual core, 8gb RAM, 1TB model looks just fine for my music / video editing needs. But I've found that there are some upgrades on the model that don't cost too much extra. Like upgrade to 16gb RAM. Will the 16gb RAM be a good upgrade? Am I really going to notice it? Following that, there is an upgrade to i7 core, but that's an extra $350. Which I don't really have. I guess what I'm asking is, as the RAM upgrade isn't too much more, would it be good with the i5 core?
