ASUS STRIX Radeon R9 Fury DC3 CrossFire at 4K Review

We gear up for multi-GPU gaming with AMD Radeon R9 Fury CrossFire, NVIDIA GeForce GTX 980 SLI, and AMD Radeon R9 390X CrossFire and share our head-to-head results at 4K resolution and find out which solution offers the best gameplay experience. How well does Fiji game when utilized in a CrossFire configuration?

Introduction

It is time to dig deep and find out how AMD's Fiji GCN GPU technology performs when expanding past a single-GPU. We are of course talking about AMD CrossFire performance; being able to put two video cards together in a system to improve the gameplay experience through increased performance and added visual image quality.

This is not an easy task to perform today unless you have a lot of cash on hand. Availability of AMD's new Fury line of graphics video cards has been wanting, especially at the high-end Fury X level. This has made it physically difficult to acquire multiple video cards for evaluation. In our next CrossFire article to be published next week, we even had to go as far as to borrow a Fury X just to bring you CrossFire performance.

This realization is a factor worth taking note of because it can mean inflated prices from retailers of graphics cards, making CrossFire with Fury and Fury X a costly endeavor. That said, we weren't going to let those issues stop us in testing CrossFire performance on Fury and Fury X!

What to Expect

We have broken up our CrossFire testing into two articles based on price positioning. In today's evaluation we are going to compare AMD Radeon R9 Fury CrossFire to NVIDIA GeForce GTX 980 SLI and also include AMD Radeon R9 390X CrossFire. In next week's evaluation we are going to compare AMD Radeon Fury X CrossFire to NVIDIA GeForce GTX 980 Ti SLI and GeForce TITAN X SLI just to put things in perspective.

4K Testing

We are going to do all of this testing at 4K! That's right, nothing but 4K testing for both articles, 3840x2160 gaming for the win. This will be the resolution needed to truly test performance of AMD CrossFire and NVIDIA SLI to find out which provides the best experience. This is also important to see if VRAM capacity differences make a difference.

What We are Looking For

There are several things we will be looking for in our testing today. First, if CrossFire or SLI even works in each game to provide a performance increase. As we play each game we will also be observing the smoothness of gameplay. In a perfect world we don't want CrossFire or SLI to introduce stuttering or a jerky behavior while gaming. In order to provide a gameplay experience improvement gameplay must be fast and smooth with no pauses or lag in gameplay.

We are going to be expanding our game evaluation suite by one game for this evaluation for a more rounded look. We are introducing Project Cars into our gaming suite for today's evaluation for a total of six games.

We will also be testing under Windows 10 Pro x64 for the first time.
