Intel's upcoming Sandy Bridge-E processors reared their heads in more than one online stores by now, but recently the chips were also listed in the US where a store offers its customers the chance to pre-order the upcoming Core i7-3930K and i7-3960X.

The chips were spotted by CPU-World in the online store of one e-tailer which has listed the Core i7-3930K at $609.99 (441 EUR), while its older brother, the Core i7-3960X, can be pre-ordered for $1099.99 (796 EUR).

Just as its name implies, the Core i7-3960X is the fastest of the two CPUs Intel will launch in mid-November, the X at the end of its designation informing us that it belongs in the company's Extreme Edition line.

The Core i7-3820, which Intel was expected to release together with the two SKUs detailed above, wasn't listed by the retailer which seems to confirm the rumors that state this won't actually arrive until February of 2012. All the processors are compatible with motherboards using the LGA 2011 socket and feature support for quad-channel memory.
