Nvidia GTX Titan X 4K Gsync Review
3D Mark Vantage
Where else would we start than with the creaky old 3D Mark Vantage. A title that has been around so long that a stunning P score was once the 5000! These days if you can't get 30000 Extreme marks you'll drop off the bottom of our graphs (unless we're reviewing a value card). How times change.
What hasn't changed is the ability of nVidia to produce a single GPU that is only beaten by current multi-GPU setups. It might not be miles ahead of the 980 here, but it's still ahead.
