'Real World' Performance difference between X8 and X16 PCIe

Hi All,

Now on my HTPC I have a gigabyte (P45) mainboard with two physical PCIe x16 slots, the thing is one is electronically limited to x8. Now due to the hardware I have to go in there and the case layout it would make sense for the GFX card to go into the bottom slot (its a 9600GT). The question is how much real performance difference will I see? The machine is not used for gaming the most challenging thing for it is decoding video (up to bluray).

Many Thanks :)

x16 electrical is only of benefit to games where huge amounts of data are moving around. for windows/blu-ray x8 electrical is fine.

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
