Just wanted to put this question out there, how many of you use custom built PC's for gaming? I will be in the process of building my own PC in the next couple of months. I like the idea of specifying my own components and being able to run a high performance machine. I'm prepared for this to cost me a fair bit, however I see more benefits of building my own PC than using a factory made one. So my general questions are, who here uses custom built PC's, how much did you spend on building it and do you think it has benefitted you enough to qauntify the costs?
