GPU runs game at really low fps

[ZiCe_Corner]

Hi guys! I just built my first pc, and everything seems to be working well except the GPU. When i start games it always runs them at 5-10 fps. I dont know the reason behind this, the fans on the gpu are spinning and the leds are working. I also have my hdmi cable in the GPU. The graphics card is one that i got 3 days ago, so it should run smoothly. Also the graphics card is not detected in Task manager, but its detected in GPUz
Specs are as followed

CPU: Intel core i5-4690K
CPU Cooler: CM hyper 212 evo
GPU: RX 470 nitro 8GB GDDR5
RAM: HyperX fury 1600MHz 8gb ddr3
SSD: HyperX fury 240 gb SSD
PSU: Corsair RM550x
Case: CM storm scout II advanced gaming
Motherboard: MSI Z97 Gaming 5
All the drivers are up to date
Thankfull for any and all help

Start with the basics. Is the card seated correctly, is the 6 pin power lead connected, did you install the latest drivers for the card, did you plug your monitor to the graphics card and not the motherboard?
