I5 2500k vs i7 2600 -- What to do???

Hi Guys,

Looking for some advice from the pros! I have the following configuration and currently have a i7 2600 running at stock speeds. From what I understand the i7 2600 can't be overclocked as its multiplier is locked. I also have a i5 2500k, which the wife was nice enough to surprise me with. I mainly use the system for playing BF3 and encoding blueray files to play on the Apple TV. Should I keep the i7 2600 with out any overclocking or should drop in the 2500k? And if you do advice to use the 2500K what cooler would you recommend? I am trying to keep my system kind of quiet. Any suggestions on clock times for CPU/Memory would be great as well!

  1. Any help, would be greatly appreciated. Thank You
  2. Definitely an overclocked 2500k.

    Best cooler for the price: http://www.newegg.com/Product/Product.aspx?Item=N82E16835103099
  3. Thanks for the quick reply! I think I swap out to the 2500k. Anyone have any sugguestions for overclock settings? Should I leave my Ram at the oem settings?
  4. The non k cpus can be overclocked 400mhz. They're locked to a maximum not locked from being changed. The i7 will be faster in encoding assuming the software is multithreaded but most games only use 2-3 cores so the higher clocks of an unlocked and overclocked i5 will help more. I would go for the i7 because it is still plenty powerful for gaming even at stock and the extra threads will help in other multithreaded software.
  5. Hmm, any one else want chime in?
  6. i dont know much about the new Sb CPUS as i only got mine a week ago and still reading and tinkering about with it but im guessing if the i7-2600 can be bumped up an extra 400mhz..... id stick with that, bump its up and turn off the speed step :)
  7. Speedstep has nothing to do with performance.
  8. Well, I dropped in the 2500K and can't get it to overclock over 4.2GHZ. It won't boot, I tried raising the voltage all the way up to 1.4. Any ideas? It's been a while since I overclocked a machine so I don't want screw this up. Your assistance would be greatly appreciated.
  9. 2500K hands down!
  10. Your max. voltage is not good to be higher then 1.37V. I have an i7 2600 i can overclock nim with stock voltage to 4.2ghz. You can take advantage with 2600 because he have 4core and 8 threats wich is necesar in heavy duty work who depends to CPU.Look at the all benchmarks ,all CPU'S are tested mostly on stock frecquensy and 2600k at stock speed is the same like 2600 and is the best CPU.Ill stay with 2600.
  11. Best answer
    If you have the 2600 then Keep it.
    It should be better at encoding by a bit.
    Maybe minutes better not an hour.
    2600 already keeps up with your GPU no problem
    2500K overclocking could be super fun.
  12. Thanks everyone for you replies, it's great to have a community to bounce this stuff off of. Switched back to the i7 2600, overclocked to 4.2Ghz and I think I'll keep it that way.
  13. Sell both and get the i7 2700K ;-)
  14. i have i5 2500k and very pleased with it at stock clocks....now i7 2600k is ht enabled there will be a diffrence in performance but not much an i5 2500k with good gpu like 560ti ot 6950 will be good for gaming on 1080p but if you are geting i7 2600k with gtx 460 or 6850 then go with the i5 option bcz in gaming gpu maters most of the time abd see this to satisfy you self

    i5 2500k is very good in gaming invest more money on gpu get a high end gpu like gtx 580 :-) if you can
  15. Pell380,

    I have a 6970 now and get about 5800 with 3dMark 2011, the free version.

    What kinda motherboard you got? All I did was set my ddr timings manually and set the multiplier to 42 and just increased one at a time running IBT.

  19. better get the i5 and oc it and do encoding on the i7 comp
