Hello, I would like to buy a new PC for AutoDesk rendering but I would like to know if the current one is good or bad.

Can someone provide me with a Revit file and tell me how much time it takes for them to render the file, their computer configuration and provide me the same file so that I can compare how long it takes for me.

Currently I have
Intel 4th Gen i7, 2.00 GHz upto 3.1 GHz
5400 RPM 1 TB Hard Disk
Nvidia 840M 2 GB Graphics
Windows 8.1 Single Language

I need to know if it is good enough.

Please help.
