Each Nvidia partner will have its own GTX 560 designs right from day one. Pretty much all of them also have overclocked editions on sale. It appears that some manufacturers will even be skipping over reference-clocked cards. Below is a list of some of the GTX 560 models we've managed to round up.

Note that prices are estimates based on a search of online stores. Models which could not be found on sale have no price.

Manufacturer overclocks range from barely-there to the whopping 950MHz of Zotac's AMP! Edition. Some manufacturers will also be offering 2GB versions, but that's not really necessary for current games except at very high resolutions, at which you would probably need a more powerful GPU anyway.

The two cards we have today are from Asus and Gainward. Their specifications are listed below:

Gainward GeForce GTX 560 Phantom

Gainward's Phantom series is claimed to provide superior cooling performance at lower noise levels. The first thing that strikes us is the very short PCB – it measures a mere 18.5cm.

The next thing is the unusual heatsink arrangement. Two 80mm fans are mounted below instead of above the heatsink.

Presumably this helps to reduce noise levels. It also looks as if it might provide better cooling to the power circuitry and memory chips. Four heatpipes connect the heatsink base to the block of suspended aluminium fins. While the plastic shroud is somewhat wobbly, the heatsink itself is quite stable and the suspended portion doesn't easily bend inwards under pressure unlike some other designs we've seen.

Gainward has opted for a combination of HDMI, DVI and VGA. While this obviates the need to include any adapters, we'd rather have two DVI outputs.

Nothing out of ordinary in the accessories package.

Asus GTX 560 DirectCU II TOP

The DirectCU II brand makes another appearance here, with the same styling as before. As a result of the large heatsink the card is all of 23 centimetres long.

The heatsink used here is somewhat complicated. A secondary block of aluminum fins is suspended above the rear half ot the card, connected to the main heatsink by three heatpipes. If you look carefully, you can also spot small black heatsinks on the VRMs. Asus has put much thought into this design – one of the VRM heatsink fins is taller than the others to support the suspended aluminium fins and prevent any bending.

Unfortunately the GDDR5 memory is not actually in contact with the heatsink, which might affect overclocking slightly.

Another interesting thing we noticed: The fan above the suspended heatsink (i.e. the one towards the rear of the card) is actually shallower in order to accomodate the heatsink.

Asus has also mounted a support bracket to prevent PCB bending.

Nothing fancy here. Of course, manufacturers don't have much choice in the matter since Nvidia GPUs only support two displays.

In typical Asus fashion, all the bases are covered here. There is even a HDMI adapter which converts your HDMI port to… a HDMI port rotated 90 degrees sideways. Odd.
