The 875 chipsets have Performance Accelleration Technology built into them, which I believe is way to skip a few steps in the pipeline but keep the speed and the MB manufactures found a way to turn it on in the 865 chipest, even though it was never supposed to be an option. I guess Intel hides these little secrets incase they ever need to steal some thunder from someone else.

I was reading about graphics card manufactures like ATI and Nvidea use 3 teams on a 6 month cycle. One is working on the big new technology that about to come out (lets say the 9800 Pro). The next team is working an updated version of that card which will come out 6 months later (9800 XT) and another 6 months to build the next generation of cards will come out. The team that created the 9800 Pro will start working on a 6 month update for the new generation of card that won't be released for a year and a half and the team that built the XT cards are now working on the next next generation of graphics cards that won't be out for 2 years. I though that was rather interesting.
