i saw a page and it said its going to be $120 more than the 2600k is now, and its expected to be released 4th Q 2011 or 1st Q 2012,
I might be wrong, So far i heard is the core speed will be 3.5 Ghz, Unless the 2700k has got something magnificent to increase performance besides the ghz, I wouldn't say its worth it, Just slam a corsair h100 on and overclock the 2600k to 3.5 and there it is! You save $120 (the same performance) Maby the 2700k could be overclocked more than the 2600k, will have to wait for the release date to find out.
