    Technical Question

    It depends what you will be using the computer for. i.e. games or graphic software or just legacy software and regular use.

    Most software's today are not built to use the full potential of the higher cpu usage (aka parallel programming) so if you don't have to just go with the cheaper 4 core. IMO.

    • The "it depends" is the correct answer. What is the purpose of your project? Both will be fun projects.

      Some thoughts, BUT only you and your wallet determine the right answer:

      Gulftwown = Westmere EP.

      Check into DUAL SOCKET EP solutions. They will cost more because of complexity of design. You know: double the electronics but much lower volumes usually means higher cost and price.

      Gulftown supports instruction sets through SSE 4.1 with AES encryptions instructions if that is important.
      135 watts consumed from your power supply is fewer watts for add-in boards.

      Sandybridge 2600k
      You can play with overclocking if that seems interesting. Sanybridge might have a dual socket solution but you probably need the 2011 socket with the extra pins and cost.

      95 watts consumed from your power supply leaves 40 extra watts. You can either use that for more graphics with an addin board (gaming) or for a slightly lower utility bill and cool running (quieter fan).

      If you are careful about the 1155 socket and motherboard design choice, Ivybridge might be a direct plug in for your current board. You can be the first on your block with the new system.

      Sandybridge supports the same Gulftown instructions plus the new 256-bit AVX vector instructions. There is not much that exploits the AVX yet but there seems to be an industry wide migration to exploit new instructions.

      They are similar in base frequency, cache sizes and bus bandwidth. I think there was some improvements in the internal cache design on the chip that might be visible to benchmarks.

      Hyperthreads give you about 50% to 80% of the compute power depending the application mix.
