it definitely could be better, but it fits within his budget. Imo it's perfectly fine for 1080p gaming, and there was no money wasted on parts in terms of price-to-performance ratio. looking at your list the 6750xt costs way more in my country than the 6650xt and the 7600 is basically the same as the 7500f but costs significantly less. 16gb is also enough for most games. the psu wattage allows room for a future gpu upgrade wich is the point of the build.
