Okay, that's much more reasonable. However, for gaming an 1155 setup will still be better
. I'm not even talking about price anymore. The thread-per-thread performance of the 2700k/2600k is, for all purposes, identical to X79. Additionally, the 1155 motherboard can then be used with Ivy Bridge in early 2012 (CPU only upgrade) which will double the PCI-Express bandwidth enabling larger data transfer from those very Kepler graphics cards.
X79 will not support PCI-Express 3.0 until November 2012 at the very earliest. IB-E is planned to have the same architecture as Ivy Bridge which means that the thread-per-thread performance will again be nearly identical to 1155. By the time games can even use the extra 2 cores (the only
actual advantage to X79 aside from benching/server related things) the chipset will be obsolete.
Also, Kepler has been delayed until mid 2012 and it's unclear whether it wil be a new architecture or a Fermi die shrink. All of the currently designed Kepler cards are Fermi architecture on a 28nm platform.
