System requirements needed for unity3d to work on PC

I have a laptop with Intel i5-460M Processor, 3 GB of RAM (Planned for an upgrade of 4 GB, so total about 7GB RAM), Intel HD Graphics and more than 1.5 TB HDD, with windows 8.1. In the system requirements page of the unity, I didn’t find the needed configurations of PC required to run Unity3d. So thats why I asked here. Is my system able to run unity fine without any problem? I have a doubt about graphics. I have the integrated intel HD graphics in my system, DO I need another graphics card for unity to run smoothly in my pc. Thanks in advance.

Does it support DX9? Then it’ll run. Will it run “smoothly”? That’s subjective.

Unity will run on a mashed potato. The real question is will it run smoothly based on what I want to accomplish with it.
