I'm fairly new to computers, and I've been reading a lot of threads. I want to buy a good solid gaming computer, but I don't know where to. I know people say not to buy from alienware and also I don't think I can build one my self. I don't know how hard it is but I wouldn't like to mess up. So the only option I got is to buy one already made. I only know two websites but I don't really know what to pick. I have $900 to spend. I want to be able to play games like Battlefield 3 & the coming Battlefield 4 without a problem.
