Would a video card that is compatible with Intel Pentium 4 fit into an Intel Pentium 4 processor 516?

Basically what the question asks, because i bought one that is compatible with Intel Pentium 4 but it doesn't seem to fit into my Intel Pentium 4 processor 516, the video card seems to be too big to fit into the computer. I was just wondering if i am doing something wrong or if it is not compatible... thanks.|||The video card has to be compatible with the motherboard, not the processor. If the video card is AGP and the motherboard only has PCI-Express slots, then it won't connect. Similarly, if the video card is PCI-Express and the motherboard has no PCI-Express slots, then again it won't connect.
