We're going to be upgrading our network at work among a few of the higher end systems. We will be installing a gigabit network.
I'm currently in the process of building a new system which is a Dual Athlon MP 1900+ w/ the Asus A7M266-D motherboard. The board has 2 64-bit and 3 32-bit PCI slots.
I've been looking around at gigabit cards to put into the system and found that Linksys offers both 32 and 64-bit 10/100/1000 cards. My question is, what difference does it make between the two cards? How much of a performance or speed increase would I gain by utilizing a 64-bit card and a 64-bit PCI slot?
