Not sure if I captured all the peripherals that you need, build is below. All parts sourced from ITDepot, local online Indian vendor. Webpages before the build.
The G4560 is capable little gamer with 3.5 GHz core speed and four threads. You can upgrade to a i3-7100 but the difference is only about 11%

The GTX 1050 Ti is good match for the G4560. You could upgrade to an RX470 or a GTX 1060-3GB.
