I believe then you have ENOUGH space on TWO external display for editing your qranger styles/songs..
This are the display resolution for each VGA and DVI port:
The automatic xorg.conf script will reconize automatically the displays connected.
Note: On K10N78 is still free the PCIexpress slot, IF you install there one Nvidia PCIe card, you can have another 2 displays out ( 4 total + the MS display)
( no more PCIe available on mainboard..pity..
