from the wonderful said:
It appears I am running a 8x AGP card on a 4x Board, will this cause any
problems or will the card just run at 4x?
It'll just run at 4x. If you had a problem, you'd know about it by now.
The only compatibility issue with AGP cards is whether they are 3.3v or
1.5v, and you have to have a really antique AGP card to even trip over
that one these days.
btw, the performance difference between AGP4x and AGP8x is not worth
mentioning .. barely detectable, even with the best benchmarks, so don't
worry about it.
