The trick with LoL is to put the graphics at max settings at 1080p , the reason is that the CPU portion of the chip is so anemic that it won't really produce much higher framerates even at 720p.
same with CSGO
Remember not to use msaa at all with the APU, you can use fxaa that's it.
You need dual channel RAM, the faster the better , APU's live and die by high bandwidth, quick memory access is to the main system.
Both those games should play at 60 frames if the above is followed.
