A short preview to the conclusion: GeForce Pro and GeForce Ultra are not so
much ahead of the GeForce 2 GTS. You need at least a resolution of 1280*1024
to get notable fps difference. For the gamers who would like to play with
such and higher resolutions, the GeForce Ultra may be the right, but
expensive decision. The performance of the GeForce 2 Pro in any resolution
is not that much better than the GeForce 2 GTS's. So the Pro is not
recommended in our opinion.
