My PC is a better spec then both of them but I will still get them both on day one.
I am a gamer so therefore it is about the games to me.
Both have games I am interested in.
If however I could only get one if they released on 1st day I would go for the x1 simply because the day one games on that appeal more. It is like Kill zone and drive club vs Dead rising 3 and Forza.
Buying something just for the ram is laughable.
