Sapphire HD Radeon 4670 is my current graphics card. I am buying EVGA GeForce GTX 750 ti. My noob question is will the 750 Ti will fit into my pc? Also my motherboard is Asus P7P55-M, 400 W PSU and QuadCore Intel Core i5-750. I don't know anything. How can i tell if i have Dual-Link DVI-I, HDMI, DP 1.2 and such or anything like that so I can know if it will fit?
