Hi Flutey
If he was to get the ti it will future proof him for at least 2-4 years on any game even with low resolution.
I would agree the RX 470 would be enough but as games get more and more gpu intensive apart from planet coaster which is as you said CPU intensive then a RX 470 would be out dated within 2 years.
Besides he may well get a HD monitor one day and want to play on high end resolution etc.
