Measure / calculate GPU PCIE bandwidth

post #1 of 4
Thread Starter 
I am curious to know if there is software or some kind of formula I can use to figure out how much PCIE bandwidth I need based on what ever task I am doing. I know the slot is rated for a maximum amount like x8 or x4 or x16 but I want to know what I actually need based on what I'm doing. A lot of programs only seem to report the max the slot is capable of using.

I know that the slots are rated for maximum but I want to know for instance, right now, how much my GTX480 requires when playing League of legends or Call or Duty or Skyrim for example. What does the card need when its loaded?

Why not determine how much the max capacity is, and then figure the max possible bandwidth a 480 can use? then if the 480 can only use less then the max the slot offers, it seems like it wouldn't matter.
