If you're on the lookout for a solid performance/gaming notebook, Trusted Reviews put three of them to the test to see which one fairs best. They look at the AJP M575A, Evesham Voyager C720 Plus, and Rock Extreme CT powerhouses. At the end of the day, they all look to be very capable offerings for pretty much anything you throw at them.
In this particular scenario, we have three laptops all based on the same Clevo chassis. However, all three companies have done different things to make their laptops stand out, from bundles and pricing, to unique etchings and overclocking features. It is worth noting, that all of these laptops are fully configurable, so if you want a slightly different specification then this is easily done and can make a dramatic difference to pricing. Some companies may want a lot more for upgrades than others.
