The Palit GTX 260 Sonic did not disappoint. The expectations I had based on my experience with the HD 4850 Sonic was that the Sonic edition cards were very overclockable and delivered exceptional performance. That this card did. At times it fell behind but the majority of tests showed it to be a worthy competitor to the Sapphire HD 4870 1GB Toxic edition card used in the performance comparison. The cooling solution is a custom designed piece that works quite well. The maximum temperatures I saw in my testing under a heavy GPU load was 66 degrees Celsius with the fan speed controller by the driver. When the fan speed was moved to 100% the maximum recorded temperature dropped to 58 degrees. This cooling solution works and works well.
