TechPowerUp posted a review on the Palit GTX 780 Super JetStream 3 GB
A quote from the article:
Palit's GTX 780 Super JetStream is one of the highest clocked GTX 780s on the market. In our testing its performance beats GTX Titan, yet doesn't break the bank. With a retail price of around $670 it is cheaper than any other custom-design, overclocked, GTX 780 card.Palit GTX 780 Super JetStream 3 GB @ techPowerUp
