There is also an 8GB version: MSI Gaming RX 480 8GB of this card available for $269.99.
Pro Almost silent fan, even when under a load
Under 60 degrees Celsius, this MSI Computer Radeon RX 480 Gaming X 4GB card doesn't run it's fans which means that it runs completely silent until you start pushing it. Under a full load, it measures in at 38dB(A)s which is extremely quiet for such a powerful graphics card.
Pro Stays fairly cool even when pushing it hard
The highest temperature recorded on this RX 480 Gaming X card is 73 degrees Celsius. This is just below average for other RX 480 cards, and is low enough that thermal throttling shouldn't be an issue (generally 80 degrees Celsius is considered throttling territory).
Pro Good performance relative to other RX 480 cards
The clock speeds are above average, which will increase performance over what the other cards can provide. The base clock speed is 1266MHz, and the boost is 1316MHz. It is faster than the significantly more expensive Gigabyte AMD Rx 480 8GB, but is just a touch slower than the Asus Dual-Fan Edition and Sapphire RX 480 8GB cards.
Con Low memory clock means slower performance
MSI have stuck with the default RX 480 memory clock speed of 7GHz on this card while virtually every other RX 480 card has been overclocked to 8GHz. This means that the card's read speeds are slower, and will decrease the performance of this card.
