What GPU and CPU do i need to run cs go at 1920x1080 at 300+fps?

I currently use i5 3570 @ 4.4 / gtx 680 2GB / 16GB ram and a SSD.

While playing a match i usually get around 150-200 fps at 1920x1080 resolution.

What GPU and CPU should I get for steady 300+ fps in normal 5v5 competitive mode?


CS GO option - Shadows High, Textures High, 16xQ CSAA, Anisotropic 16x, Multicore Rendering On

everything else low / disabled


Thanks
