So really want to know if there's much actual difference in what these do as to doing rendering. I hear a lot about cuda helping make everything go so much faster but I can't see what it gives you over open gl. Thanks if anyone could shed any light on this

Cuda/ open gl?

They're not really comparable.
CUDA is a parallel processing architecture and opens up graphics processors to be used for general purpose number crunching.
Open GL is a graphics API for drawing pretty pictures on the screen, eg Quake, AutoCAD.

Maybe you mean Open CL and not GL? Essentially they do the same thing, except that Open CL is, as its name suggests "Open source". To use CUDA you have to have an nVidia graphics card. CUDA has a limited life span because the way things work, those who make applications will want them to appeal to as many customers as possible.
yeah as Magicboy said, CUDA is basically good for number crunching, loads of CUDA GPUs would be useful at a place like CERN in switzerland for example, for use with the large hadron collider to map particle traces and what not. don't think it has anything to do with open GL or anything else graphics related 
Very unlikely.
Like i said to OP, depends upon what you are doing
well being the same person, I'll be doing vray rendering
well £4200 is slightly too expensive haha
