IF you have no other cards in the box OR you have a dual-bus system with ONLY the gig card on one bus, you might squeeze through. 32bit PCI cant do sustained 1 Gb/s transfers, so your longer packets will have problems making it through. Its simply not suitable. Its like doing 100BT on ISA. If you have a hard drive on the same bus you have no chance.
