Depends on what resolution you want to play. My i3 530 rig with GT 440 card manage to pull 1080p World of Tanks on 32" bravia with lowest setting. Never played LOL though but I think it'll do fine even with medium settings.

I wonder why AMD is thrown out of the window when it comes to budget gaming pc. Sure performance vs watt favor intel's but it's not night and day.

For me the downside of having an AMD is the cost for the long run, RM/watt, making Intel's a better choice. It's cheap and will not bottleneck much unless it's CF/SLI. I have a budget i3 gaming rig pulling 100fps, 1080p with the lowest settings and 40fps medium sets throughout my fav game. As for APU, I see it as only for backup gpu in case the main fails so in that case I save RM60. But that's the same for an i3 530 which in SuperPi trumped my current a8 5600k 11mins vs 22 mins for 32M trials.

As if I'm backpedalling but what I got going AMD route is having the best motherboard Gigabyte can offer for A85x vs the best for intel x79. It gave me a pseudo sense of satisfaction that I've bought a top end in its class. And to my relief my OCd 5600k is 15% better than ocd i3 530 in single threaded test. It's not that bad. In real life use, it just took 1 minute of my life more but I can live with that. Fayboyism "Intel is for noob", illogically put. hahahha
