I have absolutely NO interest in spending $5000 on an adapter for the $150 card.
Elendill, did it work? I am still struggling to solve this issue myself. I purchased an Aluratek VGA to DVI/HDMI adapter... Insanely strong in terms of build quality, can't get anything to my card! If you found a solution then I want to jump on that bandwagon.
Also, if it works for you, what frame rate and resolution are you capturing at?
