Will my CPU bottleneck my whole system?

I'm planning to get a Phenom II x2 555 and I want to unlock the 2 cores... but if it doesn't work will it lower the performance of my HD 5770?

I hear that you can lose a good 20 fps in gaming if you dont have a good quad core processor for the most recent games...

Should I take the chance or drop another $60 on a quadcore?

  1. Who told you that?

    Most games run perfectly fine on a dual core, the only game i know of that really requires a quad is GTA IV because it was poorly coded. Even if your PII 555 is bottle necking you it will be over 60 FPS so it wont really matter.

    Not at all. It will work fine.
    Anyway, that cpu overclocks very well and it's a pitty not to do it.
    Moreover, You have a lot of probabilities for unlocking those 2 extra cores.
    The Phenom II x2 555 is a great choice.
  3. Cool thanks for the replies both of you! I got the black edition (Its only $4 more ahaha) so I can try unlocking the 2 extra cores (I do lots of video editing on a pentium 4 which takes hours) so its more of a bonus to get a quad core for $100 because Im used to a single cored 2.6ghz processor.

    3.2 ghz is FAST and theres two of them!!!
  4. If I do unlock the two cores I cant really afford to overclock as the aftermarket hsf wont take it very well, and I want to have a cold cpu. I might very SLIGHTLY overclock (To 3.4-3.6ghz) if I cant unlock the cores.

    If I dont overclock should I be okay still? (Stock speed is 3.2ghz btw)
  5. Sorry This is my last question what is the speed of light in GHz? What is the highest possible speed of a cpu before it reaches that speed?

    I dont know if that makes sense, but Im curious to know when I'd need to make another upgrade too in the future.

    Don't worry. It will already work fine.

  7. Hell, a 3ghz Athlon II X2 probably wouldn't even bottleneck a 5770 (in most games). Let alone a Phenom II.
