    Graphic card and USB delema!!!!!!!!!!!

    I bought a Nvidia FX 5200, which was supposed to handle the video for the headunit (all the controls for CF) , and the s-video port, which was supposed to send video to 3 other monitors. The FX seems to be laggy, no matter what. I purchased the dual pci riser made for highbandwith, but I am worried it will still be laggy, even with that riser. The other card is a USB card which i think is helping to make lag on the graphics card.

    What can I do to fully get rid of lag? I was thinking of putting in a ATI Rage XL (8mb), connecting the main screen to that (the screen with CF), then connecting the 3 monitors to the onboard screen, but I remember in the past the onboard card was even more laggy.

    I would like to avoid taking out the Nvidia FX, but if i have to I will. Do any of you guys have the same setup, a dual pci riser with a graphics card and another pci card. I have the best drivers for the card!!!!!!! Maybe I can use the onboard card for the head unit (CF) and the FX for the other monitors?

    Second is a question on USB. Is there a bandwith limit per USB port? Because I was thinking of using the PCI 5 port USB for low bandwith stuff, so the graphics card has more priority. Then connect a 7 port usb hub to one of the boards onboard ports and connect all the high bandwith stuff. The hub will be powered via car adapter. 2 of the main devices include a Sierra Air Card and belkin 54 g wifi...........

    Please, someone help, this issue is becoming a big headache. I was trying to show my mom the PC by letting her watch Transformers and it was so laggy she said, "this is what youve spent almost $2,000 dollars on?" I was not happy with that remark at all.....

    If you're onboard video card is displaying lag/choppy media playback then i'd be looking at the CPU.

    Is there a bandwith limit per USB port?
    USB supports three data rates:

    * A Low Speed (1.1, 2.0) rate of 1.5 Mbit/s (187 kB/s) that is mostly used for Human Interface Devices (HID) such as keyboards, mice, and joysticks.
    * A Full Speed (1.1, 2.0) rate of 12 Mbit/s (1.5 MB/s). Full Speed was the fastest rate before the USB 2.0 specification and many devices fall back to Full Speed. Full Speed devices divide the USB bandwidth between them in a first-come first-served basis and it is not uncommon to run out of bandwidth with several isochronous devices. All USB Hubs support Full Speed.
    * A Hi-Speed (2.0) rate of 480 Mbit/s (60 MB/s).
