The CPU is, by default, running in its stock speeds. You have to enable/manually overclocking the i7-4770K, if your motherboard supports it (such as using a Z87-chipset or Z97-chipset motherboard). If you use a non-OCable motherboard (such as the B85-chipset you mentioned), the i7-4770K will only run in its stock speeds.
If you are entirely sure you won't be needing such overclocking features (which you haven't done so since you had that CPU before), then the B85 motherboard will do - primarily, due to the unavailable Z87/Z97 motherboards in your location, and secondarily, the stock speeds of the i7-4770K is enough for you.
Yeah, no need to upgrade the GPU to a GTX 1060 if your budget is tight. I am merely indicating how powerful your CPU can be, such that, in case you decide on getting a better GPU in the far future (when you have enough funds for it), you don't need to change your CPU for it to be able to handle GPUs that are more powerful than the GTX 1050 you already have.
