is it possible

i have bought 12 month ago a compact presario7468 amd k-62 which unfortunately does not have an agp slot. i tried searching around for a motherboard upgrade but compaq tells me there is no such a thing.
the only other solution i can think of if to buy a second tower with agp slot and network it so my current presario handles the general running of things and the second one handles all audio and video side of the system. is it possible. have you any advise.
thanks
