New GPU unexpected low fps

[Autocon487]

So I've changed my old GPU which was a EVGA geforce GT 740 SC to a ASUS Geforce GTX 780 direct CU II OC. Installing was normal, but my fps was worst then before. I have tried many ways such as using the nvidia control panel, downloading and using precision XOC, or even uninstalling everything that is Nvidia and reinstalling my new drivers. I'm slowly leaning towards to my new GPU is defective or something. If there's any other solution I would love to know.

CPU: AMD Phenom II X6 1055T
motherboard: MSI 970
PSU: Evga 750 Powersupply
Ram: 16 GB

It is. My monitor only has a vga cable though so I bought a dvi cable and plugged it in my new gpu. My monitor is a HP.

I'm sorry but could you explain why?

if you dont plug the cable in to the graphics card, it will not use the graphics card.

instead you will use graphics of the IGPU from the cpu.

So I should get a HDMI cable instead the one I'm currently using

I dont know if your monitor supports displayport.

otherwise yes get a hdmi cable (doesnt matter which version , the cheapest cable u can find in the store) and plug it into your graphics card.
