Crysis 2 PC minimum requirements question?

So I've just been wondering, if I played Crysis and Crysis:Warhead on Very High Settings, should I be able to play Crysis 2 on my PC? I went to Can you run it? and it said that I can't because my pc doesn't meet minimum requirements. But it also made mistakes a couple of times-it said I can't and I could. I really prefer pc, but I'll buy xbox version if I really can't run it.
