Mass Effect 3's PC version is exclusive to Origin. If that doesn't stop you from buying it - and really, it's grounds for complaint, not boycott - you're going to need to know if your PC can run the thing first.
Well, of course it can. The underlying tech behind this game is nearly five years old. So if your PC could run the first Mass Effect, chances are it can run this one as well.
