Competition is a complicated thing. Sometimes, in order to win over your arch rival, you also need to step into their products. Nvidia is now doing the same thing. The company announced today that it’s finally bringing SLI support to AMD platforms — specifically, upcoming motherboards based on AMD’s 990FX, 990X and 970 chipsets. Those will be offered by ASUS, Gigabyte, ASRock, and MSI initially, with additional manufacturers said to be coming on board “shortly after.”
And the reason for Nvidia to enable SLI on AMD’s platform might be to conquer the multi-GPU market, as they’re very close to it, according to Steam. As of today, 93 percent of all multi-GPU systems in use today use SLI, according to Steam statistics.
