then back the fsb down a little bit. can't you change the speeds of PCI and AGP induvidually?
If your board has the options for it it can. Mine doesn't, but I don't know about beedubs, the ABit NF7-S2 for example allows you to set your CPU:AGP:PCI ratio which by default I believe is 4:2:1 so you can either change the ratio to it's appropriate proportion which if your FSB was at 200 would be 6:2:1 or also in the case of the ABit board mentioned you can simply 'Lock' the AGP and PCI bus's so that they stay at their PCI:33 and AGP:66
So check your BIOS options beedub...check for an AGP or PCI Bus lock option or see if you have ratio options. It'll be in a set of 3 CPU:AGP:PCI just like that. Like I said by default it'll probably be 4:2:1 but I'm not sure what your computers full specs and defaults are.
