NVIDIA GeForce GTX 1070 Ti
vs
AMD Radeon RX Vega 56

Our Verdict: Upgrading from RX Vega 56 to GTX 1070 Ti is not recommended as it is less than 30% of improvement in performance. In general, a reasonable upgrade is between 30% and 50% or more to justify the purchase of new hardware.

Game Performance at selected quality settings

NVIDIA GeForce GTX 1070 Ti / Core i7-7700K @ 4.20GHz

With some tuning, the GTX 1070 Ti makes the most sense for gamers with 4K monitors. Though serious gamers hardly play at 4k. In terms of memory, the GTX 1070 Ti 's 8192 MB RAM is more than enough for modern games and should not cause any bottlenecks. In short the performance is exceptional, there's no question that this is one of the most powerful single GPU out there in 2017 .

AMD Radeon RX Vega 56 / Core i7-7700K @ 4.20GHz

It is clear that the RX Vega 56 is a significantly more capable high-end card that can play AAA titles at 1080p/1440p with 50-60 frames per second. It is worth noting that the RX Vega 56 is a very power hungry card and requires a decent power supply unit. In terms of memory, the RX Vega 56 's 8192 MB RAM is more than enough for modern games and should not cause any bottlenecks. In short the performance is exceptional, there's no question that this is one of the most powerful single GPU out there in 2017 .
