No!!! dont get the DFI!!! sorry but if your wanting an overclocking mobo then the best out are the new asus boards. and as you have bought a nice x1900xt then there is no point getting an SLi board. Get the ASUS A8R32 MVP Crossfire Deluxe. I have it and its amazing, never had a problem with it. You will be easily able to overclock and use 2 different (or the same) ATI cards. So not wasting money on throwing away the x1900xt when ur done with it.
