I'd just get a new CPU/board/RAM at this stage. Either move to Intel and go with a Skylake i5 or i7 and DDR4 RAM or wait for the next generation AMD CPUs which will also use DDR4 RAM. It's not worth pumping money into AM3 or AM3+ these days.Also I checked the drivers i'm fully up to date already. I've got the Crimson edition thing and i'm thinking about upgrading CPU but idk what my mobo can handle.

turn the tessellation down. AMD aren't great at this.
