Autodesk Revit Architecture

I am looking to upgrade or buy a new Desktop PC that is capable of running Revit Architecture 2013 with ease particularly with regards to performing the highest quality renders possible. I have read the system requirements and looked at two off the shelf options however I would be grateful for some feedback on which is the better option particularly with regards to rendering and the graphics cards.
