TechPowerUp posted a review on the ASUS GeForce RTX 4090 Matrix Platinum
A quote from the article:
The ASUS ROG GeForce RTX 4090 Matrix Platinum is the best RTX 4090 you can buy. For $3200 you get performance that's considerably faster than a plain RTX 4090, similar to what we're expecting for RTX 4090 Ti. Our review also confirms that the ASUS watercooling solution does a fantastic job at keeping the card cool and running at low noise levels.ASUS GeForce RTX 4090 Matrix Platinum Review
