Be warned that the first post has conflicting information - it says that a minimum of 768MB video RAM is required - but lots of cards on the list only have 512MB or less, it's a non-OS X specific list pulled from Wikipedia. So try it and find out for yourself if your video card works or not and please report back.
Confirmed, works for me too. GTX 460 added to the list.
For the record, my video board is a GTX 460, it is not listed on your tutorial. Please see the image attached.
