I now have the NEO4K with the CS3 and want to upgrade to CS5 I do not have a cuda graphic card so is there a realtime engine in CS5 and is it woking the same as in CS3?

You don't need cuda, but it is a nice bonus. CineForm works well with or without it.

Thanks David can you explain to me what you mean by nice bonus?

1. If i would work with cineform without cuda is the editing going to be realtime also if i apply an adobe effect or cineform effect on the file do i need to render it out then?

2. If i would work with cineform with cuda is everything going to work realtime even if i use an adobe effect or cineform effect on the files?
