3DMark is an essential tool used by millions of gamers, hundreds of hardware review sites and many of the world’s leading manufacturers to measure PC gaming performance.
Futuremark say “Use it to test your PC’s limits and measure the impact of overclocking and tweaking your system. Search our massive results database and see how your PC compares or just admire the graphics and wonder why all PC games don’t look this good.
To get more out of your PC, put 3DMark in your PC.”
The 1080P and 4K performance numbers from 3DMark put Asus' R9 390X STRIX DC3 OC slightly behind the performance of the same company's GTX 980 STRIX card. This should make for an interesting comparison given that the Nvidia-based card is a little more expensive at around £400.
