I7 870 w/P55 vs i7 920 w/X58

I have reached that deciding point in my build where I need to decide whether or not to go with socket 1366 or 1156. I don't plan on doing much overclocking of my system at this point. I'm looking for solid reliability and out of the box performance. I will only be using the single GTX 295 card so having multiple PCI-E X16 slots is not a concern. I am using an Antec P183 case which supports the CPX power supply I have selected. Here are the two builds I have put together right now...


Socket LGA 1156 Build:
Intel Core i7-860 Lynnfield 2.8GHz LGA 1156 95W Quad-Core Processor Model BX80605I7860
GIGABYTE GA-P55-UD4P LGA 1156 Intel P55 ATX Intel Motherboard
Antec CP-850 850W Continuous Power CPX SLI Certified CrossFire Ready 80 PLUS Certified Modular Active PFC
Mushkin Enhanced Blackline 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Dual Channel Kit Desktop Memory Model 996652

Total cost: $694.96


Socket LGA 1366 Build:
Intel Core i7-920 Bloomfield 2.66GHz LGA 1366 130W Quad-Core Processor Model BX80601920
EVGA 141-BL-E757-TR LGA 1366 Intel X58 ATX X58 SLI LE Intel Motherboard
Antec CP-850 850W Continuous Power CPX SLI Certified CrossFire Ready 80 PLUS Certified Modular Active PFC
CORSAIR XMS3 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Triple Channel Kit Desktop Memory Model TR3X6G1600C9

Total cost: $803.96


As you can see there is a $100 difference in favor of the 1156-build over the 1366-build. However, the 1366-build has 6GB's of triple channel 1600 RAM as opposed to the 1156-build's 4GB of dual channel 1333 RAM. Of course the 1156-build also has a 140MHz advantage over the 1366-build in processor speed as well as turbo boost to assist it in applications which can't make use of all 4 cores.

Which of these two builds would you go with or what would you change?

    I would go with the first one. The motherboard you chose has the LOTES socket, so no problems there.
  2. What makes the LOTES socket more desirable over other sockets? I've read a few things about burning with the foxconn socket but that's the only reference I've seen to the LOTES one.
  3. Like you have read the foxconn socket has been failing when overclocked and possibly when not. The LOTES brand socket does not have these issues.

  4. Cool, thanks for the information. That is an added bonus I guess lol. :D
  5. No problem. Good luck with your build.
