Hi
I am no expert on anything but reading this reminded me my Phablet ( Phone crossed with a tablet ) has a Octa Core A7 CPU too.
The SOC however is a 1.6 GHz mediatek and has a Mali 450 GPU.

If you go look up the Antutu, 3Dmark, Android bench marks you will see performance is very average!
( yes I know it is a different soc with different GPU, also how a SOC CPU is implimented affects performance too.)
Listen to others peoples warnings and don't fall for the Octa Core hype!
