Mark confronts the realities of mobile gaming as addressed by XMG.
The XMG brand is one owned by Schenker Technologies, and the C504 was engineered for it by hardware expert Gigabyte.
Whoever is actually responsible, this is a rather well made laptop that uses a combination plastic and metal skin to deliver a good sized machine that's just over 2kg in weight.
The balance for any mobile system for gaming is to provide sufficient CPU and GPU power against battery life and heat generation. In the first two criteria, the C504 doesn't hold back in providing plenty of grunt.
