Laptop that can handle league?

Hey guys. Recently, I have decided I'm buying a laptop for college. It's gonna do things like multitasking, like YouTube in the background with half a screen on Wikipedia and the other half on Microsoft Word. Also, video editing, Blender, and possibly some music processing.

Now, I will also play league. :D

I have been playing league on my old PC, enjoyably, on SUPER LOW everything with 30 fps, 20 fps during action. Therefore, I really don't need shadows or particles or whatever jingle bells this game has. Medium, no shadows at constant 40-ish fps is perfectly fine with me.

But I will gladly also accept Low at 30+ fps constant, with action going on.

I'll play an hour or two at a time, so maybe there'll be some concerns with heating? Idk.

Budget is less that $500. Remember, I really don't play any other games anymore. A laptop for college that runs League as a side-effect is what I need. I don't need to run crazy things like Battlefield or anything.

Leave Amazon or retailer links if you can. Thanks.
