With the older set of drivers and at 1440p resolution, Nvidia GTX 980 Ti was ahead of the R9 Fury X by around eight percent. The similar thing goes for the GTX 980, which was ahead the Radeon R9 390X by around two percent while R9 390 was ahead of the GTX 970 by around one percent. The R9 285 was ahead of the GTX 960 by around four percent. At 4K/UHD resolution, AMD Radeon graphics cards behaved a bit better but GTX 980 Ti and R9 Fury X was pretty much at the same performance level.
With the new set of Windows 10 drivers and at 1440p resolution, there is no difference between the Radeon R9 Fury X and GTX 980 Ti. The Radeon R9 390X pushed ahead of the GTX 980 by three percent while R9 290X got ahead of GTX 970 by almost nine percent. At 4K/UHD resolution, the R9 Fury X jumps ahead of the GTX 980 Ti by around five percent while the R9 390X is also faster than the GTX 980.
Bear in mind that these are not the promised Radeon Software Crimson Edition set of drivers which will bring the Radeon Settings control panel, meant to replace the Catalyst Control Center. Although AMD said that the new drivers will not bring any significant performance improvements, it will be interesting to see how will AMD graphics cards compare to Nvidia counterparts when the new driver is launched.
It appears that it might be wise to upgrade to Windows 10 OS if you are running any of those earlier mentioned AMD Radeon graphics cards.
