Beta vs VHS, Firewire vs. USB, HD-DVD vs. Blu-ray, and now FreeSync vs G-Sync. Who will win? Nvidia G-Sync is the bigger dog in the fight. Their graphics cards dominate the market 2:1 but G-Sync requires an Nvidia chip which adds $100 - $150 to the cost of G-Sync monitor. AMD's FreeSync is for the most part free. Manufactures don't need to buy anything from AMD and so there is no additional cost to the consumer. From what I've read both perform the same although AMD will point out the G-Sync takes a 1% performance hit in the frame rates.
