You're going to have issues running it..I'm running:
core2duo @ 2.2
in my laptop, at the lowest settings, it is still a little choppy, but not unbearable, I can pvp fine with highly positional characters.
At the lowest settings, with grass density down all the way and view distance all the way lowered you MIGHT be able to run it..but regardless it is going to be choppy imo.
And by the by, Strikin's post was more than adequate
The only way you'll know for sure is to actually run it.
