Your DB needs sound more hardware intensive than anything. Your queries
sound simple and I would bet you would never need to use anything but
mysql. Also keep in mind that mysql/php/apache etc run on more than just
PC's. There is some serious hardware out there that can handle
unbelieveable amounts of traffic....of course non of it is intel based
:) If an Intel box can no longer handle the load, you can split your
servers so you have one running a web server and another handling the
DB, or simply move to some real hardware. (ie HP/Sun/IBM unix boxes).
