The faster your processor, the lower your latency. I don't understand exactly how this works, but it seems to be the consensus from the articles I've read. So if you use kills switches, drum pads, or any rhythmically-responsive control while you perform music, you will benefit from getting the best processor possible. If you only use EQ knobs and volume faders on your MIDI controller, it might not affect you so much.
Similar for music production. If you want to use CPU intensive plugins, like physical modelling synths or virtual analog synths and effects, you will also benefit from having the fastest processor possible within your budget. The faster it is, the more effects you can use at any time, and the more notes polyphony you can achieve with virtual analog synths.
When people say you don't need an i7 for DJ and music production purposes, it means you can DJ and produce music with a lower spec processor. It doesn't mean you won't benefit from getting the fastest one you can afford.
