It's been my experience that if you give more than 2 weeks notice, the company finds an immediate replacement, and you are out the door. They won't/don't want you around for that period of time that you aren't in full work mode.... Wait for the raise, and tell them when you are 110% sure you are leaving. Not before, otherwise you may be home for Easter, instead of Memorial day !!! Remember, you are a "highest paid" employee. They can live with a few learning curve mistakes for less money on a newbie.
