Naresh Patre Thank you. I've found some sustem requirements for SpaceCaim, but not from your link.

I probably won't using Discovery Live in the future, because I'm not dealing with any kind of calculations. Just 3D modeling, however sometimes I work with bigger models with many constraints or - as I mentioned before - I have to make big patterns with multiple holes etc. and often I need to modify them.

So in terms of GPU it would be wise to buy at least Quadro P600/P620. What about CPU? Does it make any sense to pay more for i7 instead of i5, or in this case it will be wasted money?
