Its basically like the others have said.
You can use a 4x AGP in 8X AGP slots
You wont be able to run at the full speed though is you use 4X
Also I have notice that when I upgrade my customers systems
there are two types of AGP slot ( you can tell by the notches)
If you card has 1 notch, check your systemboard will work
with it.(The card will not plug into the AGP slot)
All new AGP gards now have 2 notches to be compatible.
