Multi monitor help

Hi everybody, I need help. 

I have 2 1080p monitors and a 1024x768 monitor. One of the 1080p monitors will only work with dvi, the other will only work with hdmi. The 1024 monitor is a vga. My question is this: if I have a r9 280x graphics card, will I need an active adapter to connect the third 1024 monitor? I am not trying to setup eyefinity, I just want the multiple monitors. (I would need a display port to vga adapter for the third)

get a displayport to dvi cable for the dvi 1080p monitor use the hdmi for the hdmi 1080p monitor and use the dvi to vga that came with your graphics card on the dvi port for the vga monitor.
