Help upgrading PC for use with fusion

[jimskeet2002]

Hi guys

I will soon upgrade my PC. It will be a gaming PC but I will use it for Fusion360 too.

I would like to ask if an I7 7700K would have a big difference in performance in fusion over an i5 7600K.

I am thinking about the i5 but if the i7 will give a reasonable boost to Fusion performance (Toolpath calculations, sketching with a lot of splines etc.) I will might go for the i7.

Toolpath calculation and rendering will benefit from more cores\threads. You will not see any benefit from more cores in the model workspace or sketch but the extra clock speed from the i7 will help.

Here's a thread on the CAM forum with some benchmarks done on toolpath calculation.

Thanks.
On sketching I sometimes see that when I trim for example a sketch with a cross hatch pattern that has like 200 lines crosshatching with each other I get like 3-4sec between each click and the finish of the trim calculation. Wouldn't there be an improvement with a faster cpu on cases like this?

Yes some but with a parametric sketcher there's a lot going on so it's always best to keep the sketch as simple as possible and make patterns with features or faces.
