I got my computer a weeks before. I mainly use it for REVIT and Auto CAD. When I'm rendering my projects, CPU utilization is 90-100%, and it uses 25% of RAM (16GB total), But QUADRO K620 is never more than 1% mostly 0% !!!

My Configuration is,

Processor: Core i7 4790K,

Mobo: Asus Z97A,

RAM: 16 GB Corsair Vangeance  8*2),

Graphics: Nvedia QUADRO K620 (2 GB).

In revit architecture 2014 Hardware accelarator I always see "UNKNOWN VIDEO CARD" 

HOW TO GET BENIFITED FROM MY GRAPHIC CARD? I did not find any specific driver in Nvedia for Revit 2014 for my card...

Revitcity is a great source but for many things Revit, you should look first in your help.  Here is what that says.

I have the same K620 card.  Its just a little new and is in the Autodesk preferred video card range.  You will have no issues with this card, on Windows 7, 8 or 10 running Revit.  Revit 2013 on Windows 10 has a few glitches but you should be fine.

The benefit will be when CHOAS Group finally releases Vray for Revit.  It'll pull much more than you might imagine.  Only get the high end cards if you plan to do high performance computing.
