I know the i3 is tempting, but with the game performance that you are going to get at an RX 6600 level, you can get close with a 4c8t i7 for cheap. Well... at least in the usa, l don't know how the used pc market is in your part of the world, so it depend.
But hey! If you could spring for an i5 13400f or something close, go with that.
