"But Nvidia said sales of its other GPU category, including the Tesla line for high-performance computing and the Quadro workstation chips, also delivered healthy results"
I can't say I'm surprised. As somebody who buys endless numbers of Quadros, it makes me all warm and fuzzy inside knowing I'm responsible for paying a 300% markup on a cheap GeForce card where the only real difference is the driver.
And before you say "so buy GeForce instead", their performance is absolutely crippled in our 3D software. Trust me, we've tried almost everything on the market, including AMD. Both companies have us bent over.
