  1. I'm asking this question because I have been looking forward to buy a new graphics card, I'm a new ,and I don't even know if you can connect a graphics card to a PCI, instead of the AGP slot? thanks!

    you can use regular pci but agp is faster and x16 is the fastest bar none

    This the board in question ? (Going by your system specs.....not sure what the "199GB RAM" is all about)

    If so, then look for a PCI-E (PCI Express) graphics card.

    Um, yes, I do not know if I have a agp, but your saying that you can connect a graphics card to a PCI E. also, would it be better if I connected it to a PCI E X 16? thanks!...and really good job finding my mother board...XD

    Yes, PCIe x16 is the default slot for a graphics card.

    Some older motherboards can have compatibility problems with cards that use the newer v2.0 / v2.1 PCI-E specification. It isn't common but can happen. If the card you are replacing is v2.0/2.1 then you'll be fine. A quick search hasn't turned up any compatibility problems, and most reviews pre-date v2.0.
