I need desperate help, my EVGA GTX 970 ssc will not fit into my case. I have a Corsair 450D, and i know thats more than enough room to fit it but on my mother board, i notice that the PCI-E slot wont lie up with my cards and it wont fit. I have a Gigabyte z170x gaming 3. Is my motherboard not compatible? How should i take care of this problem?
