Here's the latest on Gulftown...
I wasn't expecting clocks that high! 
Possibly an exclusive early launch in Feb. for Apple?

There's also some early clock-for-clock benchmarks from ES sample chips here if you missed them...

Without further ado, the official name of Intel’s flagship 32nm desktop chip is Core i7 Extreme 980X. News of the confirmation comes from Chinese-based site PCOnline.com.cn which claims to have an official revised Intel roadmap in its hands. Judging by the image, the roadmap does seem valid and official with an “Intel Core i7” logo slapped above the X58 architecture layout image. On another note, the site states that the new flagship desktop chip will run at 3.33GHz, which basically makes it a Core i7 Extreme 975 with all the quirks of the 32nm Westmere family architecture and two additional cores.
As an Extreme Edition chip, the Core i7 Extreme 980X 3.33GHz will likely be priced at $999.
several sites have stated that the flagship desktop processor will be launching in March 2010, otherwise known as late Q1 2010

We got a few additional details on Intel's first desktop six core CPU codenamed Gulftown. This is Intel's first six-core developed in 32nm Westmere architecture and it will be clocked at 3.33GHz.
This is the same frequency as Core i7 975 and even the Turbo clock on these two CPUs is same, as Core i7 980X will overclock to 3.6GHz. Its QPI speed is set to a well known 6.4GB/sec and the CPU can take care of twelve threads via its support for Hyperthreading.
We already wrote that good old socket 1366 should be enough to fit this six core CPU and one disappointing part of the spec is that triple channel memory is again limited to 1066MHz memory, at least officially.
The CPU has 12MB of cache and a TDP of 130W. According to the latest information we got, it should debut in Intel's March price list for $999.
Despite being listed for the price list in March, it doesn’t mean that end users will be able to get one.
