15 2500K vs i5 3570K

Hey everne,
Im building my first gaming pc and I was wondering whether I should get an i5 2500K or a 3570K?
I am going to be using a Z77 motherboard also.
I want the pc to last for quite a while and I am not planning on overclocking it too much so that isn't really a large factor in which one I will get.
I can get the i5 2500K with a Z77 motherboard for around £250 and I can get the i5 3570K with a Z77 motherboard for around £270.

  1. If you aren't planning on overclocking a lot, then get the 3570k.

    They're generally faster clock-for-clock by around 5-7%, not a lot, but when you're not overclocking by a large margin, you would want the most performance for your money, right? :)

    Besides the performance, they're almost identical, so you can't go wrong with either option. Both are still blazing fast and are fully capable of playing any game on the market at the moment.
  2. The 3570k gives you access to PCIe 3.0 for the GPU and ~18W lower power usage.

    Between the two, I would pick the 3570 since the lower power would easily cover the price difference over the 6+ years I would probably end up using it as either a main or backup PC.
  3. PCI-E 3.0 is irrelevant IMO, unless you're going to SLI/CF multiple GPU's, there's absolutely no benefit.

    The biggest selling point for the i5-3570k, IMO, is the HD4000 graphics and LucidVirtuMVP. They would/could benefit someone greatly depending on the application they're looking to run.
  4. Thanks for the quick reply guys. Im not planning to crossfire multiple GPU's so PCI-E 3.0 isnt important. I just need a processor that will last me a long time and that will be capable of running all the latest games an programmes.
    I have heard that the 3570k heats up very quickly?
    Should I just spend the extra £20 for future proofing or should i save it and get a better GPU (im looking at the Radeon HD 7850/7870)?
  5. 3570k does heat up rather quickly, but that's only when you apply significant overclocks. Anything within the mild OC range (4.2Ghz ish) wouldn't/shouldn't give you significant problems :)

    Personally, I would just get the 3570k for the features. It's newer, faster, lower power consumption, more features, only for a small price difference, what more could you ask? :)

    On a side note, if you were to get an i5 2500k, which GPU would you be able to get? Same for i5 3570k.

    If getting a 2500k allows you to get a beefier GPU, then by all means, go this route.

    While PCIe 3.0 is not (yet) a must-have feature, there is a 2-3 FPS advantage and there may be more in the future if applications start using more GPGPU.

    But as I said in my initial reply, my personal main interest in IB is the 18W lower TDP. The extra IPC is also very much welcome.

    Very true about future applications :) If you think about the future, it does seem wise to go with something that is 3.0 ready, however, I was just looking at it from a "today's" view on things :lol:
  8. I think Im gonna go for the 3570k as it seems more future proof.
    One last question, how well would the build I am thinking about building run games like Crysis and Battlefield 3?
    My (Possible) build:
    Processor-i5 3570k
    Graphics card- Radeon HD 7850
    Motherboard- Asus P8Z77-V-LX
    PSU- 550w Watts XFX Pro Series Core Edition
    Case- Not sure, any ideas? (about £30)
  9. Swap out the HD7850 for an HD7870, it would provide a little more horsepower for the cost.

    When are you planning to purchase these parts?

    It isn't that much more future-proof than the 2500k. Lots of people still choose the 2500k today since they value SB's slightly higher overclocks on air/low-end water cooling more than IB's few new features and improvements.
  11. I wont be overclocking much and the 7870 is quite a bit more expensive than the 7850. Is it worth it or can I just OC the 7850 to perform like a 7870. ve seen the 7850 for £140 (which is my budget for the graphics card) and I have seen the 7870 for £170. Is it worth the extra money?
  12. Prices on the 77xx/78xx were dropped a few days ago so if you wait a week or two longer, the 7870 might get in your sweet spot.
  13. Great! Thanks for the info
