Building A High End Quadro FX Workstation
An anonymous reader writes "FiringSquad has an article detailing some of the differences between building a high-end workstation and a high-end gaming system. They go into things like ECC memory, and the difference between professional and gaming 3D cards. The Quadro FX 2000 coverage is particularly interesting -- the system with the Quadro FX 2000 was never louder than 55 dB!"
Large simulations (such as this, or car crash simulations, etc.) take days, if not weeks to run. Since the ECC ram isn't 100% slower (i.e. time of fast memory times two is more than time of ECC memory) there is no need to run it twice.
Anyhow, if the two simulations differ, you'll have to do it a third time to check if you get a match, and still you only know that you are *likely* to have gotten it right. With ECC the chance of getting it right increases.
