Still use it in a system I built in 2014, and with full RAM and a good GPU still holds up well.

Un procesador bastante eficiente y eficaz para su tiempo, capacidades rebasadas para los sistemas operativos latentes de su tiempo. En la actualidad se sonroja, pero no palidece ante los nuevos sistemas operativos. En verdad una joya de sus tiempos.
