Question New GPU running slow

Recently I upgraded my gpu from a EVGA GTX 1060 6gb to a MSI RTX 2070 Armor 8gb. While playing Gta V my fps began to drop below 60 fps and in some parts of Gta V it would even drop to 40 fps on Max settings and 1080p. Even while playing on League of Legends during team fights it would sometimes drop below 60 fps. It honestly just feels like a downgrade from the GTX 1060.

Setup
i7 7700k
MSI z270 A Pro
MSI RTX 2070 Armor
16 GB Ram 3000 mhz
Windows 10

I really don't know what to do. I have tried updating my bios and windows. Installed the new gpu drivers. So that is why I have come here in hope of fixing this problem so I do not feel like I wasted $500 on a new graphics card.
