Your confused
It's OK though.
First, yea, that ram will work with that Mobo. Its just that 1066 is the max that the mobo can handle( idk if that;s the reason).
2nd, DDr3 ram is not worth it right now. And, a dd3 videocard will work with ur mobo, because of the connector it uses. For ex, the 8600gt is a PCIex slot card. As long as the mobo has a pciex slot open, everything would be ok.
