Ernie,
I do not like to discuss the computer. I can say only one thing. Hardware of my i7 64-bit system optimizing for graphics performance, rendering and 3D modeling. I had no freezing cases with other software. Even resource-intensive programs(CAD modeller, subdivision and sculpting soft) are running flawlessly.

My XDP11 hangs pretty often. For example today. I tried to convert a grunge vector brush to shape. Result: blured full screen interface and timeless loading spinner.

Yes, this brush was quite difficult. But I think, that the 3D model with 10 millions of polygons require a lot more resources than vector brush. It is a fact.

Sorry, but XDP11 does not create the impression of a stable version. Every day I use this program and I'm pretty well aware of the weaknesses.
