AGP Bus overclocking

[El Norm]

Hey i read at tomshardware that having an overclocked agp bus is good sometimes. for example on a bx board running at 133 mhz with only a 2/3 divider would make your agp somewhere around agp 2.7X. so i'm wondering if overclocking your agp bus to the highest possible setting would be a good idea or not. say i can run my computer just fine with a 1x multiplier and a fsb speed of 112. would this help my performance and has anyone actually tested this to see if there is any significant performance increase. appreciate any info or insight any one has, thx in advanced.
