(let them see this) A graphics card is pretty much the key to gaming with a computer. Your son wont be having any fun with his new computer, if it doesn't have a graphics card. I mean if you want to play on your computer, you'll need a graphics card to handle the new games. A PC without a graphics card is like buying a car without wheels (kind of a crappy comparison but it will do
). You are just not going to get that far without one.
And a good 200dollar card like the RX 480 will last him years with good quality and performance in the upcoming games.
What components are in your PC?
As mentioned above, the RX 480 may be overkill, but the 950 may be underpowered!
Depending on the price it can be a different situation.
As mentioned above, compare it to a car, but rather than wheels there's no engine!
Without a graphics card a desktop PC is just a google and email machine.
