No doubt, the best there is. The best costs money, expect to spend. Expect problems, they are inherent to Windows and being on the cutting edge. Dell has great support, vastly improved after the acquisition. Know what you are buying, there is a difference between a laptop and a mobile workstation. If you dont know the answer, you might be the person that is referenced in the saying... and his money are soon parted.
Its a gaming machine. If you are not a gamer and lugging around a 16lb mobile workstation, its not cool, you just became that guy.
Its the best for performance, enjoy it.
