    Hey folks

    Have a 7970 card and notice that quite often if having a video on one display playing, it causes my system to become sluggish and choppy. For instance if you were to drag a window you can see it's unsmooth.

    Or the video will begin to lower in frame rate if the other display is smooth if that makes sense?

    Lowering the resolution of one seems to help but surely the card is powerful enough to have them both run at 1920x1080? My old 6850 could handle it.

    I'm on the newest drivers and connect one screen by HDMI and the other by a DVI-HDMI cable.

    Specs are as follow:

    Processor : Intel Core i7 2600K @ 3400 MHz
    Physical Memory : 8192 MB (2 x 4096 DDR3-SDRAM )
    Video Card : AMD Radeon HD 7900 Series
    Mainboard : Asus P8H61/USB3
    Operating System : Windows 7 Ultimate Professional Media Center 6.01.7601 Service Pack 1 (64-bit

    Really at my wits end in terms of how to solve it, so any help at all would be greatly appreciated.

    Attached is also an image that shows some weird graphical issues on the left side of primary display that sometimes happens
