FPS not improved?

Hi guys!
So, today i installed a Asrock 7700xt and had a 5500xt. I used to get around 100fps in ancient and now I'm only getting around 200. I feel like thats VERY low for the massive upgrade that this is and considering that my brother with a 6750xt gets more than 300fps in some cases. My cpu is a ryzen 5 3600 and my ram is ddr4 16gb 3200mhz.

Should i upgrade ram or cpu? Or could this be a software problem of some sort?
