I'm trying to determine if my new computer will play this as is, or if I need to look into getting a dedicated graphics card. 

It's a Dell Inspiron 3847  with Intel (R) HD Graphics 4600.  

This IS my concern,

as the rest of the computer seems fine with it's Intel i5-4460 quad core 3.2 GHZ, direct X 12 with 12 GB or RAM.    

OR  

Do I need to buy a new video card and power supply for it?    If so, what can/type for someone with a limited budget is good for this game?

Thanks in advance.
