The moment you look at the Moto G turbo edition you would be mistaken for it to be the Moto G3 since they look exactly the sames. The only difference is between the processor and the battery charging.
So now the Moto G Turbo has snapdragon 615 with the same 2GB RAM and due to this the phone performs much better in gaming than what we saw on moto g3. Also the battery now supports turbo charging and the quick charger is bundled in the box.
The camera is same on both the phones, and it is good! Also the display is same on both the phones, too.
I would say if you really are a gaming nerd then you should definitely prefer the turbo edition over the regular moto g3. But if you want to save some money the Moto G3 is still a good option to buy!
