I somehow doubt their fan is powerful enough to keep the system under 105 degrees Fahrenheit through hours and hours of straight gaming.
The max the asus has gotten to on battlefield 3 with ultra settings was 69 degrees (Lol I'm a perv but its true). Idk about the MSI.
Also the Asus has 2 fans.
Alienwares are AWESOME if you can get there best one. Like the m18X maxed out or there desktops.
