I just looked at your specs. You need a whole new system. A new CPU and a better GPU. I would bump your ram up to at least 16GB. I should have paid more attention to them before. I thought maybe you messed and meant i7 8700. Your CPU is pretty much obsolete. Sorry but that's the truth.
I know no one likes to hear it but you need to upgrade.
Of course you could keep the GPU and just use it till you can afford something better. Since you are using hardware that dated I am going to take it that you are strapped for cash. So keep the GPU for now and look into a new CPU and some more RAM. You will probably need a new motherboard.
