Some folks are saying to buy a 7900GTX instead of the 7950GTX because they're the same card with different factory clocks. Do these other differences (highlighted in red) make any difference?

Yep. Those stats highlighted in red are simply because of higher clocks.

Well, what was stated originally was for the most part correct. The differences are based solely on the clock differences. However, the cards obviously arent the same as they would have a compatible BIOS. The 7950's generally can overclock further. The significance between in-game FPS however will be insignificant.

voltage i believe has to do with the clocking further.

The voltage has nothing to do with the memory clock. And thats what many 7900's are incapable of setting: high memory frequencies.

As far as I know the 7950 has a higher core GPU voltage and HDCP capablities vs. the 7900. That should be it.

I just don't know if the HDCP change is a silicon core change or a just a switch turned on that was already there.

The 7900GTX uses the 1.24 Volt I think where as the 7950 uses the 1.32 which gives it the juice needed for th ehigher frequencies. As far as cards are concerned there essentially the same card.
