    i5 750 better than i7 920

    tons

      I don't get it how i5 750 can have better DDR3 memory support ? look at comparison http://ark.intel.com/Compare.aspx?ids=37147,42915

      i7 920 says DDR3-800/1066 and i5 says DDR3-1066/1333

          Different motherboard / chipset architecture. The i7 9xx series has the memory controller on the processor die and supports up to 1066 MHz. The socket LGA1156 processors are designed to run with the P55 chipset and use the old FSB which supports the higher 1333 MHz memory bandwidth. A lot of debate out there right now over which is the better approach. Lots of review sites out there that have published comprehensive benchmarks and I'll leave you to draw your own conclusions, but any differences seen are generally pretty marginal. Personally I think the biggest advantage in going with the socket 1366 systems is having true x16 PCIe lanes but I recently put together an i5 system for a friend and was fairly impressed with the performance of what was a budget build. Unless you plan to move up to i9 whenever they appear, I think either option should serve you well.

            But don't understand why memory companies build 1600 Mhz+ memories and say specialy designed for i7, best performance for i7 etc... and i7 like doesn't support it....

              Coz if you overclock you will get 1600 RAM speeds
