I currently have a very old PC that only just scratches the minimum requirements. In a couple months I will be getting a new pc which will be very capable of playing Sins. I want to know if i buy Sins for my current pc, when i get my new pc, will i be able to transfer the game over?

As im in UK so itll b expensive and time consuming to have a hard copy shipped over (unless anyone can recommend a website that will ship quick and cheaply) . I really want this game now as it looks great but I dont want to have to spend another £22 when i get my new pc and want to experiance the whole game on full graphics.
