The Precision workstation model line, though, changes less frequently as of early 2012, for example, we still occasionally purchased new Precision T3500, T5500, and T7500 models. In May 2011, for example, when the OptiPlex 790 shipped, we stopped buying the OptiPlex 780. Historically, Dell changed OptiPlex models every 12-18 months, and we switched to the latest models immediately. * These are the approximate years that the models shown first became available.
