Look on the net for WCPUID.exe.
It tells you CPU speed and info and includes an AGP tab which tells you what the board is capable of and what it is currently set to.

ok i now know it is 2x which i am pretty sure is not that fast. but if i get a new ati 9700 pro that 2x will slow the card down wont it. it would be the same as getting a lower end card.
