As a "Linux Gaming Review Site", perhaps something you could do an article on would be the 'perfect linux gaming system'.

You have reviewed various hardware components, and even some notebooks, but no 'ideal linux gaming system' has ever been shown.

After all, it may be possible that the 'perfect system for Windows' would differ in specs (such as motherboard, cpu, gpu, nic, etc) from the perfect Linux gaming rig (due to hardware support or various other performance optomizations present).

Obviously gaming speed + quality + compatibility + reliability would be important from various angles, but other issues could be raised, such as hardware running hotter on linux causing stability problems, or lack of driver support on linux ruling out certain components etc.

Pretty much the article could answer the question: "What would the best possible Linux Gaming Machine be today, and what would it cost?".

Just my 2 cents.
