Look, on final all I want is a recommendation for what laptop and where to buy them cheap. If you don't want to talk about second hand pc's then I'm sorry but that's got nothing to do with the thread
It's your decision, I've already told you why it's not smart. I honestly don't care what you get, was just trying to help.
I have a hp8440p with 8gb ram and an i5 in it and it's pretty good, I can run 2 clients or 1 client + skype + fraps
