I would like your input from your experience or ideas regarding server or workstation-class processors compared to similar desktop processors. Is there really a difference in performance or reliability enough to warrant the often price premium for these platforms? Now obviously each has their own advantages and disadvantages. Desktop processors can be used for overclocking and are usually slightly cheaper clock-for-clock, but server-class processors can often support dual-socket platforms and greater amounts of RAM. So for the sake of comparison lets assume a few things: 1) No overclocking: All components of our theoretical systems will be run at stock specs and speeds. 2) Single socket: If only one processor is used in this system, will there be a difference in performance if the processors are generally identical in specifications (Xeon vs. Core i7, or Opteron vs. Phenom II X4)? 3) Design use: The system will not be for gaming or multimedia needs but purely for graphics design and similar design work. With this in mind, is there really an advantage or disadvantage with a server-class platform over a similar desktop platform? It's my general experience that the server-class platform is going to bring with it a higher price premium even if the general specifications are very close. And if there is a performance advantage towards the server-class platform is it enough to even warrant this difference in price? Is there better reliability or lifespan in the server-class platform?
