Will he make it?

Hey everyone,
I hope I found the rights forum for my request: Im fairly new to PC gaming and would like to know how well my PC can handle the game.
Its specs are:

  • 4 GB of RAM
  • Graphic card: ATI Mobility Radeon HD5850 (1024 MB )
  • Intel Core i5-540M (2,53 GHz)

Is running it at medium, 30fps possible? Im really interessted in Grim Dawn but dont want to play at super low settings only. Will I face problemes during big battles (AOEs etc) with multiple enemies at once?

Thanks for your time.
