So my brother wants to buy a gaming PC for himself, but I suggested that I just build one for him so he can save a little bit of money. He usually just plays Dota 2 and some other lightweight games, and other stuff he does is mixing music for fun and just browsing the interwebs. So I decided that an i5 6600k might be just right for him, but considering that he won't be needing overclocking or the full power of a i5 6600k, I thought that it might be too much for him performance-wise and price-wise. So is there any skylake cpus you guys could suggest that would be just right for him? If you could throw in a good suggestion for a motherboard for it it would be great too. Thanks
PS: I just thought some of you may be wondering what GPU I'll get for him, its a 970. He's not really a big fan of AMD lol.
