Dunno, never had a pc that was that screwed for it to be a concern:/

IMO it should be more than fast enoughm but I'm not sure if the software will work, as I doubt the developer tested it on the assumption that the mouse would be connected this way.

If not just go USB to PS2, you proabably won't reach 250, but defo more than 125.

Let us know!

Yeah ps/2 goes up to 200hz.

the hz on the PCI port are low so i think it might bottle neck.

I think im not sure cba researching.

33.33 MHz clock with synchronous transfers

Technically, he should be fine, if he puts the mouse at 1000hz then that's only 1KHz.

I think it should be possible. There's nothing I see about PCI that would not allow for it.

Using PCI is a direct violation of AGP standards and will not be sanctioned

Punishment is -5 points.

thanks for the help. since it seems possible i'm going to give it a go and pick me up a card from the store right now. i'll post my results shortly

could some someone link me hertz ocing software for xp sp3. I recall there was one that only changed the mouse hertz and didn't need rebooting.

It will work, the operating system will see the new USB-controller just as the ones integrated on your motherboard (which is connected by a PCI-bus too by the way). You will only be "overclocking" the polling rate between mouse and USB-port by using the "usbhidf" program, which will work on driverlevel (and so is able to only affect the human interface device).

Works for XP, Vista only in "Test mode" (guess Windows 7 is the same - has the same kind of driver signing-crap).
