the GeForce 9600 GT's implementation is strictly identical to that of the 8800 GT (PureVideo 2). On the other hand, new PureVideo HD functions have been added via the 174. drivers, which were made available to the press only for the 9600 GT. There are four improvements: dynamic enhancement of color and contrast (the exposure of each frame can be corrected via the histogram, meaning that it's calculated 30 times per second), simultaneous dual-stream video decoding (Picture In Picture is supported, though with new versions of the players), and finally the possibility of keeping the Aero interface when playing HD video
In practice, we examined the differences using several films - we weren't able to make captures of HD films - and the only one we thought we could discern a difference in was Full Metal Jacket, Chapter 7, where the detail in the backlit shadows seemed a little better with the 174. drivers (due to the improved contrast). Even here, the difference didn't really jump out at you. That makes sense, since the masters for HD movies are especially carefully prepared, and unlike a TV signal, with HD there's not much that needs improvement
Αμα δεις και τα benchmarks, μια χαρά τα πάει και στα παιχνίδια... χαλαρά καλύτερη από 3580, κοντραρει στα ίσια την 3870, και είναι κάπως χειρότερη από την 8800GT (πιθανότατα καλύτερη ή ισάξια με τις 8800GS / 8800GT@256).
