Does anyone have a website I can look at different computer builds in certain price ranges? One of my friends is looking to upgrade his computer, for gaming, and only looking to spend around $700. I tried helping him but haven't really kept up with computer hardware so not sure what to get for the price. He told me that he thought about doing SLI'd 9800GTs but I recommended that he do one GTX260 or something. Just not sure on the motherboard/cpu (he wants a quad) and other parts. Thanks in advance.
