re: Quitting on my boss

If your boss gives a shite about you at all he'll be happy you're getting a 60% raise/advancing your career. If he values you as an employee he'll try to match that or get close enough to it to get you to stay. If he just gets mad or talks about how you are crippling him/the business.. he's not worth working for anyway. From what you said it sounds like he's a good guy so give him the two weeks notice and bust your arse for those two weeks to help find a replacement.
