Gaming computers are supercharged computers equipped with powerful graphics cards and other components to handle the demanding processing demands of modern games and streaming.
Most gaming computer companies have intense requirements to receive a gaming sponsorship and very few offer open Affiliate programs. With a large enough audience, you should be able to get sponsored by any of these companies. If you are a smaller creator, you will have to look to a company like Xidax to join their open Affiliate program. Make your determination based on your audience size and the gaming computer you yourself would use.
