By your post I guess that you are thinking of buying it. If you can, post a reply about what you want from the phone? Game or normal usage?
Gaming: The GPU in this phone is not the best out there but can give a decent experience if not the best. Obviously, small games like Temple Run 2, Subway Surfer, etc will run smooth and probably no lag as there is also a 1 GB RAM in the phone. Running a little graphic intense games might not be the best, but it is still playable. I doubt games like NOVA 3 will run on this phone.
Video: Can play 1080p videos, but recording is just 720p (is what I heard, not sure).
Has a 720p display with ~294 PPI pixel density which is good enough!
The 1.2 GHz quad core processors (Cortex A7) is more than enough for running the Jelly Bean OS based smartphone, and the smooth and buttery feeling of the OS itself will add to the pleasure of using this smartphone. And Jelly Bean has Google Now which is fun to use. :)
If you are a lover of big displays, then this phone is just too good for the price the company is offering.
Hope this Helped. :)
