Hello! I'm thinking about ordering a Late 2015 iMac 5K i5 3.3ghz w/ R9 M395 GPU. If someone here has this model or has one with an i5, can you answer this question for me? How does the i5 handle multitasking? I can't decide if getting an i7 is needed. I will be doing some light video editing (1080p) and I would like to be able to do the following at the same time; 1) Use an elgato HD60 for console game recording 2) Watch a video (Netflix, Hulu or youtube) 3) Web surfing 4) FaceTime. If an i5 can handle all this that would be awesome as I don't want to spend 2599 to get it with an i7. Thanks for the help!!
