Buying a new laptop

I would recommend the ASUS, yes as the u series i5/i7's aren't very different. The Lenovo has Windows, whereas the ASUS has DOS. Do you plan on gaming? if not there may be better options.
 
The laptop will be used for some games(bot the newest ones) and for some work in autocad and ofcourse normal use(browsing, word, etc...). It doesnt need to have windows installed.
