Performance Issues due to the game or my setup?

Hi all,

I’ve heard a lot of mixed conversations, I’m running the game on Ultra and from the spec I have I should be able to run it absolutely no problem in theory. So my question is, is my spec not good enough or is the game just game related due to the way it has been created? I am getting around 40-50FPS at best on Ultra. Most people say SLI is dead so how can the best GFX card and a high end PC not cope with a game like this?
