Intel Core i7-990X Extreme Edition vs. Core i7-2600K
 

Intel started integrating the new Sandy Bridge processor microarchitecture not in the upper price segment, but in the mainstream LGA1155. This resulted in internal competition between the new LGA1155 and the old LGA1366 processors. So, which one will win in this round, the progressive Sandy bridge or the previous-generation Gulftown?
