The Palit 8800GT I am using whines if I overclock the shaders quite high, not the GPU or the Memory just the shader. If I run the shaders at default speed the whine goes away! 
It's not a biggy as the card is very stable and not to hot (65°C Furmark load) but I can't say I heard this from a Radeon before . . .
It's not the sort of thing I would complain about or think of an RMA etc
