I'm looking to upgrade to VISTA and the Vista Upgrade Advisor software said my old 3com card won't work without a new driver and I'm sure this card is so old that 3com will not write a driver for it. What I would like to know is if anyone can tell me if an INTEL PWLA8391GT NIC card will work with VISTA? It is the latest GBit NIC on Intel's web site but it doesn't mention anything about VISTA. Secondly, if it will work with VISTA can anyone give me any pro or con advice regarding this card? I'm looking for something from a name brand company that is going to be supported as opposed to some no name brand. Lastly, if there is a better pick of NIC's to use in this situation I would like your input and reason why you believe this other card would be a better buy.
