I needed a better CPU for a not very up to date PC. I checked the compatibility list and searched ebay for this one. It came quickly, was incredibly easy to install ( DELL 745 desktop) and has boosted the speed of the PC a bit. I previously tried a singe core 3GHz Pentium but it was glitchy with strangly slow response times. This dual core, tho' much slower clock, behaves well and gets the job done.
