Hey there,

I'm a bit of a noob when it comes to graphics cards and stuff.

I have a Dell Dimension 8300 comp, i'm upgrading my graphics card and i'm looking at either a Radeon X800 series card or NVidia 6800 series card, theses are all PCI-e cards. Is this compatible with my motherboard??

Or
Is there anything i can do to check whether it is??, also how do i know if my motherboard is SLI compatible??

Any help would be much appreciated

Thanks
