ASUS GeForce GTX 670 DirectCU II 4GB SLI Review
 

We review two ASUS GeForce GTX 670 DirectCU II 4GB video cards in SLI under NV Surround resolutions. We'll answer the question as to the value and validity of 4GB of RAM on a GeForce GTX 670 GPU video card in SLI. Far Cry 3, Hitman Absolution, and all our other games will be taken to the extreme to get to the bottom of 4GB GTX 670 cards.
