Super Pi is used by a huge audience, particularly to check stability when overclocking processors. If a system is able to calculate PI to the 32 millionth place after the decimal without mistake, it is considered to be stable in regards to RAM and CPU.
This test showcases the excellent single threaded processing performance of the system.
ASUS do some great gaminmg machines too, and they cost a lot less than Alienware, but at least Alienware put a lot of effort into the looks as well, which is important.
Great machine, I own one, been using it now for gaming for a month. runs a bit hot on my knee, so I use it more on a desk.
The problem with Alienware laptops, of which I have had many, is the hinges wear out so soon. If anything needs replacing it is absurd at costs.
