It would seem that the folks at techPowerUP! really liked the MSI GTX 780 Lightning 3 GB they just reviewed. Here's a quote from the review on overclocking the card: MSI's new GTX 780 Lightning is built to provide maximum overclocking features for enthusiasts and record breakers. It comes with a large overclock out of the box that makes it faster than GTX Titan, yet still has more headroom inside. Our manual overclocking yielded another 14% performance increase.
