Just got my 750ti. Do i need to install CUDA ?

So i just got my new card because my ATI one couldnt cut it.

Ive installed the drivers, jumped into Blender, and I cant select CUDA only OpenCL.

Do i need to download something ?

I took out my other card so the 750ti is the only one in there.
I guess I will have to grab something from graphical.org because I dont understand any of that github stuff.

I watched Tigrrr’s video and it looks like i am going to get great speeds once when i can get it to work. Probably the best $200 ever spent.

append: just grabbing the one made by Rolf.
(thanks Rolf)
