HD 6870 Inquiry

Hi guys, i own a Sapphire HD 6870. My PSU is a generic 600w. The system is running fine and stable, meaning no random shutdowns of whatever. My mobo is has a PCI-E slot v 1.1.

Now my question is, is my PSU hindering my HD 6870 to deliver its full potential or is it my mobo that's hindering it? I have this question on my mind for weeks now. I am worried that I am not maximizing my cards full potential. Thank you for your answers!

  2. No. Either you get enough power and it works, or it won't boot/run at all.
  3. the pci-e 1.1 can possibly limit it just a tiny bit.

    So if my system is running, that means, my power supply is enough? and even if i change my power supply, it wont improve my CPU's performance?

    Yes pretty much. Unless you have instability, like random crashes, changing the psi will not increase computer performance.

    If you want more speed consider over clocking your CPU. The 6600 were pretty good back in the day.

    It's just that I was getting better frame rates when i was still using my 6770 and after i upgraded to HD 6870, my frame rates somehow dropped. at first i was getting random crashes and shutdowns but after i installed the drivers, it did not crash anymore but like i said i am gettng lower framerates compared to 6770 and that just aint right :(
  7. Sounds like the driver issue never got resolved. I'd suggest using driver sweeper or similar to get rid of the drivers and reinstall the latest drivers from AMD.
