I don't see an outright question here. I see mention of some model series but no exact model from those series. Try asking about a specific game on a specific model from those series.
CAD is usually fine. That is, it may not be instantaneous but it should be fine.

im hesitating between the lenovo x1 carbon and the lenovo w540. im a mechincal engineering student so the laptop will have to be able to run CAD programs, and if possible run some games.
i would rather buy the x1 since its lighter and i will be carrying it around allot, but im afraid that it might have some trouble running some of the programs as it's not as powerfull as the W540.
