GeForce FX 5600 Ultra
This "accelerated" version of the NV31 was significantly different from the usual one.
First of all, this chip required a completely different PCB design, with external power supply from a PSU, BGA memory layout and more powerful cooling. Video cards on the GeForce FX 5600 Ultra, by definition, were more expensive than their counterparts on the regular version of the GeForce FX 5600.

The problem was not only the lack of software that could fully realize the potential of the card (DX9), but also its insufficient speed. At the time of the release of full-fledged DX9 games, the card could no longer provide an acceptable picture at the proper performance level in comparison with its competitors from ATI.
