So, to sum up: the 9700 is exact the same as the 9700 Pro, expect it´s running on lower core & memory frequency.
Increasing the core frequency shouldn´t be a problem, but most models are equiped with cheaper ram (3.6ns = 275mhz). Don´t expect to see the memory go as high as a 9700Pro.

A 9500 Pro is the same as a 9700 pro, but the memory bandwith is cut in half. Still, this cards remains very powerfull and can be compared to a GF4 Ti4600. It even outperforms it when FS AA is enabled.

The 9500 non pro is a 9500 pro with 4 of the 8 pixel pipelines disabled. This results in a major performance loss, which makes the 9500 Pro a better buy. However, the 4 pipelines are DISABLED, not REMOVED. A simple software hack can re-enable these pipelines AND double the memory bandwith to 256bit. Basicly, this software hack turns your 9500 non pro into a 9700! We will go into this later on.
