Is my i3 3220 holding my 7850 2GB back?

    I have an i3 3220 along with an overclocked 7850 2GB (1150/1225).

    In Sleeping Dogs with VSYNC OFF, I'm not always getting maximum GPU usage. Does this indicate a CPU bottleneck?

    I'm under the impression that the GPU should ALWAYS be 99% GPU usage, but I notice that mine fluctuates between 80% and 99% on Sleeping Dogs.

    Can anyone please advise?

    Thanks

    Nope, the motherboard is a b75. I think I'll sell the cpu and mobo I have now and get the i5 and b77. Good idea?

    Thanks for confirming guys. I have been helping Tom overclock his gpu in the graphics section (amd overclock thread) and i thought he had a slightl bottleneck but i wanted some other confirmation before i told him to buy a new cpu/motherboard. :)

    the i5 and 7950 might save you a bit of money and you wouldn't get noticeably less frames once its been overclocked.

    I'd personally just upgrade the CPU to a 3570K. The 7850 graphics card is very capable, especially when overclocked. It should easily see you through till at least the next generation of graphics cards.

    So just go for the cpu then guys? I'm not bothered about ocing the cpu for now so the motherboard is okay to stay as is?

    Also how can I be fully sure it's bottlenecking?

    Ok, so a few things.

    When I put AA on extreme in Sleeping Dogs, GPU Usage is always 99% - Does this still resemble a bottleneck?

    Will a STOCK i5 3570k bottleneck with my 7850? Will I see a noticeable performance increase?

    Cheers

    It's does run ok, it can dip in the 30's which is annoying though.
