Hi, thanks again for looking into this.. you are right, the calculator has a flaw in calculating intel CPU's.. we are testing to see if it's all of them, or the particular 3930 you've mentioned.
For a scene like Philippe described, it should be around 1500 points to render, and we are offering very good discounts on bigger package plans.
If anyone is interested to test the backend, I can add like $100 credits into your account, just send me a PM.
