Is this laptop good for High-end games?

It's okay. It will run the games, but if you're looking for beautiful graphics; no lag.

I suggest you pick something else. Otherwise, look at reviews to see if it's worth getting it.

Should be

It's not the best to be honest. But laptops arnt at high end gaming.
(A GOOD gaming laptop is usually worth around a minimum of £1000)

You should be able to run those games but not extremely well.

I'd advise you improve the…
CPU to a quad core. Preferably Intel.
The GPU to a nice Nvidia GTX 660 or above.
And the RAM should be Atleast 8GB.

Hope it helps.

Yes.
