All good things eventually come to an end, and now that Sandy Bridge has gained some major traction, Intel has decided to end production of its LGA1366 Core i7 processor line. That includes the enthusiast oriented Core i7 990X, a six-core processor that until recently was without equal in the consumer desktop market. It doesn't matter, because for most, Sandy Bridge is the sexier option, and more affordable to boot.
Intel made the announcement in a Product Change Notification (PDF) and said that market demand for quad-core Core i7 930, 950, 960 and six-core Core i7 980 and 990X LGA1366 processors has "shifted to other Intel products."
The last order date for tray and boxed processors will be June 29, 2012, and the last delivery will be made on December 7, 2012. What that means is you'll still be able to buy LGA1366 Core i7 processors through 2012, which is great if you're looking to upgrade an existing build, but it doesn't make a whole lot of sense to construct a new LGA1366 system at this point.
