Should I buy the lenovo k3 note or the new moto g3?

I'm in a dilemma here whether i should go for the k3 note or the moto g3.I'm a heavy user and play games like fifa 15, asphalt 8(for the record I also play pc games like BF4, Team fortress 2, Bioshock, etc if you were judging). The k3 note has a bigger 5.5 inch screen and the g3 has a 5 inch screen. But the k3 has a full HD screen which is good and bad at the same time, better multimedia experiece but the processor is not able to handle the resolution when running heavy games. The k3 note also has a cpu throttling issue which decreases the power of the processor when it heats up and games start to lag whereas the g3 has SD410 1.4 ghz (the k3 has a 1.7ghz octacore MTK processor) which is less than the k3's so i don't know whether it would run games that well. I was also thinking abou installin CM 12 on the k3 note if I bought it because of all the bloatware it has. Would that solve the throttling problem, and would i get a better performance than the stock ROM. Or should I just go for the moto g3 (I'll do that if someone tells me it would handle games (above mentioned) without any lag).
