What a bizarre title. Sure, AMD might not be releasing as many refreshed cards as Nvidia this month, but that doesn't matter. The only thing that matters for consumers is price/performance, and both AMD and Nvidia are still overpriced.
A better title would be "don't buy a GPU right now", since the refreshes will hopefully trigger price cuts from both AMD and Nvidia.
And yeah, "fuck you" Nvidia for not releasing working Linux drivers.
