Hey there Jonata.
Unfortunately it doesn't seem like your system have the necessary juice to run the game. From what I was able to find out your computer does not cover the minimum system requirements listed on the game's website:
OS: 64-bit Windows 7, Windows 8.1 and Windows 10
Processor (AMD): AMD FX-6350
Processor (Intel): Core i5 6600K
Memory: 8GB RAM
Graphics card (AMD): AMD Radeon™ HD 7850 2GB
Graphics card (NVIDIA): nVidia GeForce® GTX 660 2GB
DirectX: 11.0 Compatible video card or equivalent
Online Connection Requirements: 512 KBPS or faster Internet connection
Hard-drive space: 50GB
Basically you could add more RAM and the GPU seems to be barely covering the minimum system requirements, but I'm not sure if the CPU will hold up. Please have in mind that those are the absolute minimum requirements in order for you to be able to run it.
Sorry for the grim news. I really know how you feel because I'm somewhat in the same situation.
Anyway, I hope that helps. Cheers!
