to regular stock clocked GTX 460 cards, Asus has rolled out two special ones with DirectCU cooler.
The ENGTX460 DirectCU TOP/2DI/768MD5 and ENGTX460 DirectCU TOP/2DI/1GD5 feature identical design and both work at 700MHz for the GPU, 1400MHz for those 336 CUDA cores and 3680MHz for either 1GB of GDDR5 memory paired up with a 256-bit memory interface or 786MB of GDDR5 memory paired up with 192-bit memory interface.
The cards use the same DirectCU cooler that has an 8mm heatpipes and offers up to 20 percent better cooling performance compared to reference cooler. Asus was also keen to point out that both of these cards support its Voltage Tweak and are bundled with the Voltage Tweak utility so you can get up to 50 percent higher performance with a pinch of voltage adjusting and overclocking.
Both cards should be available pretty soon although you can expect a slightly higher price tag due to the DirectCU cooler.
