Sapphire HD 4830 512MB
 

I very much like the dual slot cooler because I personally had issues with early HD 4850 card overheating and this card stayed cool and quiet even when overclocked to speeds higher than the stock HD 4850 cards. Sapphire was smart about the heating issues on the HD 4850 with their dual slot cooling solution and I am very pleased to see they brought it to their HD 4830 line as well to aid in cooling. Out of the HD 4830 cards I tested this one stayed the coolest even to the touch. My HD 4850 has to sit in my case for a few minutes before I even dare to remove it because I have burned my fingers on it before. Sapphire did a great job in designing and building the HD 4830 for us.
