Palit is ready to launch their custom HD4850 with 3 Phase GPU circuit and 8- pin PCI-E Power plug for better power distribution. The core is cooled with a dual slot twin heatpipe design and the GPU has been overclocked to 685Mhz, Memory to 1Ghz.
A forum user at Palit's User Forums got a chance to test one and was quite happy with the changes done by Palit.
With better performance, lower temperature, and quieter fan, the Palit HD4850 sonic completely beats the stock HD4850.AND, you don't need to spend money for replacing the stock cooler
