It's recently been announced that Nvidia will be the official graphcs (GPU) of The International 2017.  This is the largest DOTA 2 tournament held yearly and directly backed by Valve Software (creators of DOTA 2).  With DOTA 2 being a huge eSports title, this seems like a major win for Nvidia.  Several players are known to have sponsers but a direct sponsership by Nvidia with Valve should speak volumes for Nvidia sales and branding.

It seams DOTA 2 Championships and professional eSports teams such as team Liquid and Team Secret are choosing GeForce GTX 10 Series graphics cards and NVIDIA G-SYNC as their graphics platform of choice.  Not sure if this is a trend or marketing but it should boost branding mindshare for the green team.
