Your build could undergo a downsize in terms of form factor IMHO.

You could take this build into consideration.

But the build assumes you're going to migrate to the unlocked processor part under Coffeelake's banner which is why I chose the 3200MHz ram kit.

In the interest of sanity given the recent trend of outrageously overpriced GPU's and Memory. It is possible to find a 1050Ti for as low as $200.... Like so -> https://www.newegg.com/Product/Product.aspx?Item=N82E16814126170&cm_re=nividia_gtx_1050ti-_-14-126-170-_-Product

If this card is still in stock when you look at it. In today's market it is best to play the wait and purchase game with your GPU's. Look for a good deal on a GPU and when you find it grab it. It should be possible to get a 1060 3GB for ~$300 although honestly when they were released that is the price of the 6GB.... But this is unfortunately what we have now.
