I've been thinking about a PC replacement. My 4 year old Dell PIII 733 is starting to get a little slow. (Less than a 6 months after it's most recent reload) I want to get something that is top notch but still somewhat of a reasonable buy. Plus, the Alienware stuff rates real high on the cool factor scale for looks. I have no problem spending $4k on a PC if it will serve me with $4k worth of product. I've never spent that much on a PC...have any of you? What's the best PC out there these days?
