Phoronix posted a review on the NVIDIA GeForce GTX 460 running under Linux

NVIDIA formally introduced the GeForce 400 "Fermi" graphics card series in late March when rolling out the GeForce GTX 470 and 480. This launch was followed by the GeForce GTX 465 availability in late May and then in the middle of July there was the launch of the GeForce GTX 460 768MB and GeForce GTX 460 1024MB graphics cards. For the past few weeks we have had our hands on the Palit GeForce GTX 460 768MB graphics card that was sent over by NVIDIA to conduct our first tests of the Fermi / GF100 hardware under Linux. While the GeForce GTX 460 isn't clocked as high as the GeForce GTX 480 and has a slimmed down core, its performance is rather nice for being a $200 USD graphics card and is able to pack a performance punch when using NVIDIA's proprietary Linux driver.
