So maybe, somebody can answer my questions:
I am using PD8 to edit HD-movies.
Is there a difference in rendering speed if I buy Intel i5, i7 or AMD Phenom II? I don't know if PD8 is supporting Hyper threading technlogy. Is it really worth to buy Intel i7?
My other question is about the graphics card: Ati cards support the Ati stream technology. Nvidia cards support the Cuda technology.
Did anybody try PD8 on different PC systems?
Thank you very much for your help!
