I do have a passkey, not sure what this client-type=advanced is or where it should go.
I may be getting a Titan in the next few months... I do 3d rendering and have been contemplating one. It'll probably fold nice too.
it's under configure, then expert, then you add an option, the name is:
client-type
and the next field put in:
advanced
and save the configuration and you should be good to go.
and a Titan is great -- whiterabbit has 4 of them in one rig!

... a Titan gets almost 200 K ppd; a 780 around 120+... and they're both beautiful cards! (I want one too!)
