New Rig Suggestions?

[spearchucker]

Hope Ive got this in the right place, if not sorry, but anyway Im not very pc smart and am looking for a new rig. Ive been told building my own would be the way to go, but I have no idea how to do that. Just thought I could drop a line or two here and get some advice from the good people here. About the only thing I will use it for is gamming, I just want the best I can get for the money. Anyway just let me know what you think and your time is much appreciated. Just a gamming rig that will run some of the newer games good or the best to get within a good price range thats all Thank you
