MSI R4850 Video Card Review
 

The MSI R4850...what is there to say about this video card - except that it rocked! The MSI R4850 was not only able to overclock higher than the Sapphire HD4850 that I recently tested, but the MSI card was also able to stay cooler under a full load than the Sapphire by about 20°C! I was very surprised when I saw that this card was competitively priced with the other HD4850 cards that have the stock cooling solution, which adds an extra value to the card. The performance of the R4850 surpassed the Sapphire HD4850 - not by much - however, in the benchmark world, every point makes a difference and adds even more value to the card.
