A:AnswerThe motherboard only supports PC4-17000 (DDR4-2133) memory, from what I have read the memory you asked about will work just not at its optimal speed since it wont utilize the 2666 potential.
A:AnswerYou could certainly upgrade the motherboard and the GPU but it is not needed. If you really want to upgrade the GPU and feel the 1060 isnt enough then you will certainly want the 1080 ti.
A:AnswerTommiegun97,
It is possible to upgrade to an i7 processor, according to HP's website this motherboard is compatible with one i7 processor (i7-7700 to be specific). Newer and previous versions are not compatible with the pin setting and socket type. https://support.hp.com/us-en/product/omen-by-hp-870-200/13687063/model/15741160/document/c05389962
A:AnswerThis pc can run fortnite at high settings on 100 fps. This pc comes with a basic keyboard and mouse. Mouse doesnt have any buttons on side. The keyboard is not mechanical so I sugest you buy a seperate mouse and keyboard.
