Just apply the hack. Navigate to C:\Program Files\Adobe\Adobe Premiere Pro CS5.5, open cuda_supported_cards.txt with Notepad and add a line
GeForce GTX 470
to the file. Save it and it is enabled.
Thanks Harm, but it is already in there by default, and that is what I think is strange... The card is supported officially but no mercury is selcetable. I don't remmeber setting any preferences reg this in 5.0?
Should I try and update my Nvidia drivers? I currently have ver. 258.96 installed.
Definitely, because CS5.5 requires the 268+ drivers. You can now download the 275.27 beta version.
Your current driver version is the cause of not being able to select hardware acceleration.

It is actually 260+ drivers that CS5.5 require for GPU Acceleration.
Do avoid 270.61 and 270.71 though.
