I mostly watch youtube, type stuff for school, and for games i play league of legends, minecraft and somesteam games so what games could i play on this computer easily? Doesn't matter on graphic level ingame

It's a mid-tier card but more than worth it for a laptop priced around $600. I'd buy it and it would be more than enough for the games you play. I bet you could max out League of Legends. As for Minecraft you should be able to do just fine definitely.

You could play a lot of games with that card. Here's one example:

The video shows it's not exactly maxed out but good quality nonetheless that tells you could play many big titles.

This isn't a card that is dedicated graphics, rather it isn't a card at all. This is an integrated graphics unit that has no dedicated memory. It requires ram from the computer in order to operate and in fact, if you replaced your factory ram with DDR3-1866, you would actually gain performance. It has also been noted elsewhere that the performance of the HD 8650G does not improve the overall performance of the computer, even when it is in crossfire mode. In some situations, it actually is better if you run the system without using the 8650G, as the APU can handle the situation.
