ASUS GTX980 Matrix SLI Review
Here we often compare a 1440P resolution to the 4K one and see how much performance you lose in the most modern displays around. Today we thought we'd see how much extra performance you're getting from adding the extra card. If you can afford a 4K display then another GTX980 must be within your budget, and nearly every title gives around 90% performance increase from doubling your GPU horsepower. Impressive stuff from the Matrix.
