It should fun LoL fine, but I would definitely spend the little bit extra and get a 760k. It is only like 7.40 something more and worth the added cost. It is from an improved revision of that line of CPU's and has a higher clock speed. If you can afford the extra cost, I would also bump up to an FM2+ motherboard so you will have support for Kaveri should you decide on wanting an upgrade. Regardless, for sure go with the 760k.
