Any experiences with NVidia iCafe drivers?

I'm looking to buy a GTX 960 for my new desktop on the basis of it being the last with XP drivers on the NVidia site. However I'm having trouble finding one new and with warranty in my country, whereas newer GPUs are plentiful.

However I found this, a set of drivers which claims XP support and also supports newer NVidia GPUs (including the 1000 series). Is this legitimate? Any experiences?

NVidia does have a page ( for the iCafe driver set though I can't find any official download link for an old XP version, just a Win7 one...
