Is it a waste of money to buy the iPhone 6 plus?

I would really like a device big enough to do all my reading and gaming on one device. I currently have the iPhone 5 which I can sell to my brother for about $250 but I Really want the iPhone 6 plus except it's $750. That's $500 out of pocket excluding tax and phone case which would bring it up to $550. Is that really worth it?
