how many point give ...

They should give you their full store price value.

You get full value if the game is not on the bundle list and the discount is not 95% or more.

Here's the site where you can tell if steam gifts considers if its bundled or not since I too often would ask if it got bundled or not
http://www.steamgifts.com/bundle-games
And Witcher hasn't been bundled yet so you get full count of its cost.

Lol suspended ;)
