It is worth buying at 8999/-
Because the hardware/specs this phone has gives the value to every penny you have spent.
This phone is very good for a common user, but if you are buying it for gaming thinking it has 8 cores, then it may not satisfy you.
For gaming you require high speed processor rather than more no of cores, 8 cores will only help in multi tasking.
I bought in 10k and using it from 4 months, and I am fully satisfied with this phone.
