So my previous GPU was a MSI radeon 270X, and with that I got about 230~ fps in-game.

Now after a massive improvement, one should think at least, it has been lowered to about 70/80 fps...

That GPU is now a MSI RX 480 8G. And the drivers are up-to-date. CC 1303, MC 2000.

I even put the settings on low, and I still got that same result, even after restarting...

It's driving me nuts! There must be a thing I'm missing here.

Windows was newly installed after I got a new MB, 1,5 month ago.

Windows 10 64bit
MSI RX 480 Gaming 8G
AMD FX-8350 8-Core Processor Black Edition
MSI 970 Gaming
Crucial DDR3 BallistiX Elite 1866Mhz 2x8GB
Corsair CX650M, 650W PSU
Hitachi HDS7210 Harddrive

Games are tailored by card or by series of card. They display differently and that's why compatibility is a huge issue. Directx12 is supposed to address this to allow for more expansion across cards.

But as for you, the old card at the same settings might show differently as far as what's actually rendered. Something is probably different if you were to side by side compare. Sometimes this is something so subtle you might not notice.

Did you use DDU between installations to ensure full removal of drivers before installing the new drivers? If not give that a spin and see what it does.

It could be a lot of things, from a problem with your system as a whole to a problem with CSGO. You need to start from the basics. Use a benchmark program like 3dmark to test your upgrade. I like 3dmark because their website has scores for all sorts of systems. Compare your score to people with an FX 83xx/480 combo. If your score is nowhere near what others are getting, you know it's something to do with your system. If it is right, then it's something with the game.

Also, when you play the game, use something like MSI Afterburner to monitor the clockspeeds. Are your CPU and GPU running as fast as they're supposed to or are they running slower, maybe something is throttling them down.
