My GPU is a gtx 1070 ti and haves GDDR5....my ram is a G skills Ripjaws v series 16gb with DDR4..will it still work with my gpu being GDDR5 and ram being DDR4? Oh and I heard that my cpu is not compatible with my motherboard and recommend I should get a z270 motherboard. (I have a z170a motherboard.) But my ram says its a Intel z170 desktop memory model. Will my ram work on a z270 motherboard?
