My needs are not heavy (a bit of Logic X is the heaviest use I'll have). I'm a writer, so mostly I'm just after the screen here. Also movie watching, surfing etc. That said, however, a stuttering computer will annoy me to no end. I'm just sensitive that way. How much of a difference would the i7 processor make in day to day operation? Will scrolling on the web be jerky without it? I just want a buttery operation. I should mention I am also planning on 24gb RAM. What do you guys think? Would the i7 be worth it for someone like me? Or is better graphics support a better place to put my money? Also what configurations are known for causing the machine fan to kick in a lot? I like a quiet computer.
