In my opinion, it is quite decent. But hey, if all you want to do is play silent hunter, the integrated graphics should be more than enough. Intel HD 4400/5000 is surprisingly good.
The keyboard change however, is atrocious. I much prefer the old classic thinkpad keyboard over the new one.
If you would like more powerful gaming, consider this model:

It is one of the few ultrabooks with dedicated graphics.
