[Notebook] Integrated vs Low tier Dedicated

[Northside]

Looking to get a new budget 15" laptop and to get the most out of it across the board with some less intense games thrown in such as Europa Universalis 4

I have narrowed down to 3 decisions
Lenovo b50-80 with i3 5005u (integrated)
Lenovo ideapad e565 with a8 8600p (integrated)
Lenovo b50-45 a6 6310 with r5 m230 gpu

Which setup is the most effective/bang4buck?

you will get more gaming performance (a little) from the b50-45, but it is still going to suck. One thing I am not sure about is how optimized the games Clausewitz Engine is. It has been around a while but that doesn't mean it was always friendly to low performance systems like Source. I also loath AMDs notebook chipsets. These are 28nm chips that create alot of heat on load which leads to noisy fans.
