So I recently assembled my new PC and everything works except for my videocard. The weird thing is that it's detected by the BIOS and it's transmitting to my TV through it's HDMI port, yet windows dont detect it and when I play games or something it always uses my onboard graphics card (AMD Radeon HD8670D).

My graphics card is an AMD Radeon R9 270X from Sapphire (http://www.tomshardware.com/news/bitfenix-comrade-pc-enclosure,25509.html). An example of picking the onboard graphics card is systemrequirementslab, screenshot here: http://screencloud.net//img/screenshots/f5fa46d364970ad48a4393992e06cc6d.png

Yes, both 6-pin PCI-E slots are connected.

Yes, I made sure the primary graphics adapter is PCI-E in the BIOS.

I tried completely disabling the onboard graphics card.

I tried both the latest AMD drivers and when it didn't work I even tried the drivers that are on the disc. I tried putting it in my other PCI-E slot, but no effect either.

I hope anyone here can help me out!

I realize that but features like games and, what I showed, checkers like systemrequirementslab, still use my onboard one. Games that even look that good like Payday 2 run at an incredibly low framerate is one of the problems.

It detects both Videocards so for some reason there must be something that gives priority to the onboard one, but I'm perfectly sure everything in the BIOS is as it should be.
