The biggest beef I have had with the ATI HD4 series cards has been the temperatures. Moving into the 90 Celsius range is not what I would consider optimal. This is something that Sapphire has taken care of with the HD4870 1GB Toxic thanks to the Vapor Chamber cooling. When manually controlled and overclocked, the temperatures I was able to achieve were in the mid-50C range and no higher than 57C. This does come with a price. Noise. At 4000 Rpm the fan is loud. The compromise is that when the CCC controls the fan speeds the temperatures never hit 70C and peaked at 67C in my testing. A benefit to this is that the HD4870 1 GB Toxic can be overclocked right from the factory. The clock speed on the GPU was increased by 30MHz over stock with the memory 99Mhz over stock and had the potential to go even higher. The overhead on the card was pretty substantial at 107MHz and 198MHz on the memory. This offers a pretty decent performance increase over the preset overclocked performance. With performance between the GTX 260-216 and Toxic pretty similar your really have to come down to looking at price. At around $250 dollars, the pricing structure puts this card right under that of the GTX 260-216. The Toxic offers a value for the performance and cooling it delivers.
