I don't understand why the reviewer chose the lowest end alienware laptop and then mentioned cpu bottleneck as a con.
If you were going to do such a big detailed review, you should have chosen the model majority of people would like to go with. The one with i7-6700HQ, 16Gigs Ram. And also, this is perhaps the only laptop which I have seen with options to choose battery size. I think you chose the lower battery version, but if you wanted you could have chosen the 99Whr battery for $50 extra and it would have beat all the laptops in the competition. 99Whr is the maximum legal limit for batteries in a laptop! Many other reviewers said that this one has one of the best batteries in its category. 6-8 hours on regular web-browsing in non-gsync version.
Also, there is a 1440p and 4k version including one with 120hz.
