Intel has decided to phase out the first of the Nehalem Core-i7 processors - 965 and 940 which were released back in November, 2008.

The two chips have become an End-Of-Life (EOL) product within just 6 months of its release. The last date to order the CPU will be on September 4, 2009. After this it will be officially unavailable. The third CPU Core-i7-920 which was also one of the first Core-i7 chips will continue to be available as usual.
Intel said in a statement, "market demand for the same has moved to other products. Following the Core i7 940, Intel will next discontinue production of high-end quad-core 3.2GHz Intel Core i7 965 Extreme Edition.

Intel will replace these two processors with Core i7-975 and 950 which is expected to release at end of this month May, 2009.
Intel will be shifting from the 45 nanometer Nehalem architecture to the faster 32nm Westmere architecture later this year.
