Juju just send me a message with a link to the drivers I refered to ealrier:
@unknownuser said:
The drivers I was referring to are available from OmegaDrivers, it seems as though they have drivers for both ATi and nVidia these days. I remember when I had my Radeon ATi 9800 Pro 128MB (it was a few years ago) these drivers helped to speed things up, I can't think that things have changed much in assessment.
How much they will help with SU, I don't know. However the drivers were always well optimised and stable.
Hope this helps!
perhaps these can be of use for you...
