which is the best discrete graphics card driver to use with T2765-T6U.
I was using till currently only intel graphics drive with W0 at res 1440 X 900.
I installed 3470 driver but it does not provide anywhere near the above resolutions.
Sine The contraption is ripe past its average life san anyway i decided to try to run it in
exclusive discrete mode. i installed 3470 .Is there a better one.?
