7870- low performance

i upgraded from a 6770 to a 7870 and my games performance is worse.... :(
i should be getting 60 fps in the witcher 2 on ultra at my resolution(1366x768) howver this is not the case.
i uninstalled all old drivers and have the latest drivers.
cpu performance is 60%
i dont know what to do short of a complete clean install of windows.

thanks in advance for your replies

    Witcher 2 is cpu hungry. Also your lower resolution places more burden on your cpu.

    You need to overclock to at least 3.8ghz.


    Good Luck!
  2. hahaha i thought i did well at 3.5ghz.. i will try harder

    thank you for your reply!!!

    Lower resolution does not place more of a burden on the CPU. It simply reduces the burden on the GPU.
  4. make sure you mb bios is up to date..a lot of times there bug fixes for newer hardware. also make sure you download and install the newest chipset drivers for the mb. also run gpu-z and make sure the card running as fast as it rated for. ie 16x mode and not a slower 4x or 1x mode.
  5. You're gonna need like, dual 7870s in CF to do Witcher 2 besides your CPU.. Game is DEMANDING AS HELL if you wanna do ultra.
  6. hi. just to let everyone know i clean installed windows 8 and that fixed my problem. i get around 40 - 60 fps on ultra ....... i will get a 3570k in the future however thanks for all your replies(i stuck with to phenom @ 3.5 GHz as i couldn't get it any higher)
