You'd better check the release date of each GPU.
- GTX 480/470 (GF100) in March 2010: The first GeForce 4xx GPU.
- GTX 465 (GF100) in June 2010: The same die as 480/470 with (possibly defective) shaders/function units/memory controllers disabled.
- GTX 460 (GF104) in July 2010: A different die from 480/470/465, the first NVIDIA GPU supporting HD audio bitstreaming. Hardware was released on July 11, 2010 and the driver supporting HD audio bitstreaming was released on July 14, 2010.
There are no cracks to fall in between 480 and 460 (except for the numerical value of the model number), 480, 470 and 465 are all identical hardware-wise (with minor changes in clocks and disabled units/shaders/memory controllers). 460 is different. I see how ignorant *tech support* is (as usual, common to almost all companies).
As Nev said, only GF100/GF110 do not support HD audio bitstreaming (it's not a driver issue, simply necessary hardware is not on the die). All the others support it. FYI
GF100: 470, 480, 465
GF110: 570, 580, 590 (2 x GF110)
GF108: 430, 440
GF118: 530, 540, 545?
Or could be PureVideo HD. I don't know what the package designer meant by HD, and how correctly EVGA support you spoke with understands it.
