Nvidia GeForce GTX 980 SLI / 3-way SLI / 4-way SLI review @ Hardware.Info
 

Nvidia introduces the GeForce GTX 980 and 970 today, in case you hadn't noticed yet. What's the performance of these cards in tandem, you might wonder. Well, we've tested the GTX 980 in SLI, 3-way SLI, and 4-way SLI, using a state-of-the-art Haswell-E-based test platform. We tested the new cards on seven games, including Battlefield 4, Metro Last Light and Watch Dogs.
