I'm having a difficult time buying up a number of HDMI -> DVI connectors, trying to find one that will give me 120 Hz.
 
I'm using the 2x DVI outs already, and I get 120 Hz on those.  But every HDMI -> DVI I buy up (spent close to $120 on adapters), even ones supporting "Dual Link" and high resolutions - none of them give me the option for 120 Hz in Nvidia's Control Panel.
 
I posted once before: Does the 600 series even support 120 Hz over HDMI?
 
My 120 Hz monitors are Planar SA2311W.  They only have Dual Link DVI, HDMI, and VGA.  Before you go off and say, "use HDMI -to- HDMI stupid!", the manual says that 120 Hz is only supported on the DVI input.  The HDMI input will only operate at 60 Hz. 
  
Surely the 600 series cards support 120 Hz over the HDMI, right?  Am I going to be forced to get an expensive Powered Display Port adapter?  The ones that need USB to power the adapter to support 120 Hz?  Considering how much I've now spent on adapters, I might have gone that route anyways...
