Bill because I build my own servers, I build with an eye toward the future. For example, the last server I built, posted above has Dual QuadCore CPU capacity and up to 64GB RAM. I started out with a single QUADCore CPU and 8GB RAM. This means I still have room to double my CPU capacity and increase my RAM by a factor of 8.
As the cost for CPUs and RAM decreases, I can leverage my investment. So in short...build for today with an eye on tomorrow.
