I'm not familiar with the currency changes, but if I was going to recommend a $300 build to someone, this is what I'd suggest. I price checked the CPU on the site you linked and it looks like it's priced similarly to what I listed below. You should just find these components on the site you use and see if they fit your budget in your country.

You're budget limits you a lot, but that's a decent entry level cpu/ram/gpu combo that would probably let you play the games you listed on lowered settings. You could leave the power supply out, but I doubt your current one would be able to work with the new components.
If you can't afford these components, I'd recommend looking into the used market. Idk what that looks like where you are, but in the US you can find a decent i5 workstation PC for under $200 with 8 gigs of ram. Throw the RX 460 in something like that, and you've got a decent build.
