I'm running Windows 7 and I am thinking about building another computer so all my stuff will run faster and smother. I'm not sure about an AMD or an Intel? I know I want a quad system because I already have a single and dual so I need to step up one notch. I don't want the top of the line because I'm not rich so what would be the best bang for the buck? I don't know squat about motherboard but I guess it should be able to handle DDR3 memory if I want to keep it over a year. Any suggestions?
