ATI did one recently. 4770 or something. However, that was AGP 2.0. The 5700 is about seven years old now or something like that so I think it's time to throw the lot in the bin and start again on account of -
It will have a 20 pin PSU.
It will have an IDE drive set.
It will use DDR at best and possibly even SDRAM.
It has absolutely nothing salvagable at all .
