" GeForce GTX 480 : 512 SP, 384-bit, 295W TDP, US$499
GeForce GTX 470 : 448 SP, 320-bit, 225W TDP, US$349
Internal benchmarks reveal that GeForce GTX 470 is some 5-10% faster than Radeon HD 5850 and similiar [sic] for GeForce GTX 480 over the Radeon HD 5870."
That is all fail, no one in their right mind would buy a GTX 480 with a TPD of 295w over a 5870 with a TPD of 188w for a 5-10% boost, especially since the GTX 480 wont be clocking very high at those power levels.
I am taking this with a grain of salt, possibly a wishful one.
