The embedded graphics is not in the motherboard, mainly it is in the CPU,
I was recently making a comparison between the integrated graphics in the skylake processors and the old GT 9500 (check
here) which I had in an old case for my little brother, apparently the new integrated graphics are 350% better than the GT9500. but if we compare the Intel HD530 (which is the integrated graphics) with something cheap and basic like GTX750Ti, you will see it lacks behind (around 150% performance difference).
To reduce cost of the graphics card you get the 750Ti which will assist the Animation stuff, don't expect much from it but it is a good basic card.
MSI N750TI TF 2GD5/OC GeForce GTX 750Ti 2GB DDR5 Link Now in stock $144.00
(TF model has 2 fans)
As for the motherboard you can go for a better names like Asus or Gigabyte if you have concerns about lifespan
Asus Z170-K Z170 (DDR4) (LGA1151) Link $168.00
There are lot of choices but I chose a basic featured Asus board, the same Z170-A is more equipped if u want to pay extra 20$
