Viktor main here :D. Personally, I like to get a core of ...well the perfect core, a rabadons, and a lich bane. This way, you get a LOT of free ap, (otherwise it would have gone to waste) and the lichbane purchase is because you basically get free 50% ap scaling to put your massive ap pool to use, and because it give you huge burst with your Q. After these items, I go pen usually.

I go pen because, he has so much free ap (technically not free...)  on his core, that augmenting that with a rabadons is just too good to pass up. But ap will benefit you so little that pen will increase your damage more.
