I am new to PC gaming and I have playing WoW on my horrible laptop. I am getting 7-12 FPS. I was told building a computer is cheaper then buying a pre built one. I don't need to be playing with crazy FPS but I would like to get around 30 FPS on ultra settings. So if anyone could help me by letting me know what I should get to be able to play at a decent speed. I need everything. Please and thankyou.
