Regarding the second image, if there aren't three rows of 5 pins each, then it's likely a serial cable, which is pictured

I would keep the VGA, although you'll probably never need it again. When I throw something away, I usually need it the following day. Seriously. I once found a ridiculously long VGA extension cable, like 20 feet long, and was more than happy to add that to my laptop bag, which holds a collection of great goodies, like HDMI, VGA, DVI-D, analog cables--the works. I make space for it, forget about it, but have access to it when I need it, which I sometimes do!
