Video card will most likely be somewhat better than the motherboard, if the motherboard even works (cpu depending) so use a DVI-DVI to 1 monitor (most likely this'll be the primary monitor according to gpu) and use DP-HDMI for the other monitor. Both from the gpu. Just remember to also set the inputs on the monitors themselves according to which input is used, one will be dvi, the other hdmi. Whichever you set in windows as primary may or may not be what the gpu sets as primary, so it's not uncommon for bios to show on the secondary monitor but windows be on the primary you set.
