Alienware is certainly not what it used to be and a better alternative, go Clevo/Sager.
MSI certainly gives much more bang for your buck over Alienware.
Additionally, the article is a bit incorrect in calling the MSI GX60 a "barebones". Go check out some of the reseller websites that offer the "PowerPro" or "Force" laptops, those are your "barebones" laptops. Barebones is essentially the non-branded, stripped down version of the MSI branded laptop.
This article only covers the GX60, if you want more performance check out the GT60 or GT70 series which offers the GTX 680M graphics card and Intel chipset. Same package as the GX series but it packs more of a punch in performance.
