Is my Core 2 Duo E6400 @ 2.13ghz a bottleneck for a HD 4890?

Hi,

I'm currently considering an upgrade from my current gfx card, an old faithful Radeon X1950 Pro. After reading a few reviews, my heart is set on a HD 4890. My only concern is if my CPU will hold back the performance gains from an upgrade. Any thoughts?

Kind regards,
Voy.

  1. will your cpu bottleneck your new GPU? yes
    will the 4890 run circles around the x1950 pro? yes
    will you enjoy playing new games with your new card? yes
    can you always upgrade your CPU or OC it? yes
    is your heart set on the 4890? yes

    ...so whats your question?
  2. Overclock your processor a sh*tload, you can. That will minimize it
  3. Overclock your E6400 abit more.
  4. Thanks for the answers guys. I have OCed my cpu to 2.7Ghz now. Will see if I can go higher with a few more settings changes. I guess my question was if it would bottleneck the new GPU too much, not that I can do much about it besides pushing the limits on my current cpu.

    Thanks again guys.

  5. What resolution do you play in and what games do you like to play?
  6. I have the same CPU and I used to have an X1950pro. When it died I replaced it with a 4850 and my CPU was a huge bottleneck, since I hardly saw any difference in some single-thread/cpu dependent games (I am describing older versions of Source Engine btw).

    I OCed it slighlty (went to 2.56 GHz...for some reason I need to turn the voltage waaaaaaay up even for that, so I am not going for more) and you can see the difference. Everything ran much better. It's still not a beast and it does bottleneck my gpu a bit, but it's a pretty good combination.

    My guess would be that a 4870 and a 4890 won't have that much a difference in performance with that cpu. But feel free to try.
  7. Yes your CPU will limit the gains you would otherwise see going from a 1950pro to a 4890. How much depends on the particular game itself. Still, it will be a good improvement and you can upgrade your CPU latter.
  8. I would consider just grabbing a 4870, or even a 4850 for that cpu. The performance difference should be pretty marginal...

    Unless you plan to upgrade the CPU in the future! Then the 4890 might be a worthy investment.
  9. nonsens

    my case : E6600 2,4 Ghz + GTX 285
    E6600 2,4 @ 3,4 Ghz + GTX 285 ... maybe 5-8% boost

    Nice overclock BTW. It should be fine, but like others suggested that 4850/70
  11. And get a decent cooler
  12. 2.7GHz is decent, but a bit more would be welcome. At high resolutions though, games are much more gpu dependent, in other words, it would be no big deal to stay at 2.7GHz. When i say high resolutions btw, i mean at least 1680x1050, usually higher. I'm sure there are some comparisons done by tomshardware that can show you the differences. All in all, i'm saying go with the 4890.
  13. take a look at this article... a bit old but still says a lot.
