Here are the passmark results for my pc. I7-5960x Clocked to 4.5 Ghz.. PCI-e NvMe c-drive. Notice the drive speed @ 13633. A normal ssd is about 3500-3900. PCI-e ROCKS!!! I'm a firm believer that when I upgrade I go to about the top of the line. I run HUGE drawings. The one i am in now is about 25 MB and only into the end of preliminary's. No framing, etc.
