I'm starting a YouTube channel with a friend doing gaming videos, I won't need to edit as he does this. The i3 4150 is £50 cheaper than the i5 4430 so in just gaming it's an obvious winner but when recording I'm not sure? I have a comparison here (The i3 4150 is a renamed i3 4330) please don't suggest AMD FX processors, I'm using mini ITX and an Athlon won't cut it.
