BENQ FP767B or FP791

I have seen a lot of good comments on the FP767B around and I had alook on the BENQ site. They have another one which is the FP791, does anyone know what are the differences between them and if it is worth more then the FP767B.

i believe that the only major difference is that the FP791 supports DVI input, and to me, that would be a reason to choose it over the FP767. Otherwise the two are just about the same, probably the same 16ms screens, maybe with different backlighting or something of the sort. If you dotn have a DVI output on your video card, or dont want to use DVI, go with the FP767, otherwise spend the extra hundred or so and get the FP791. (www.buy.com has pretty good prices on the two, www.newegg.com should also)
