Hi There! I want to upgrade the network at my house, currently 100Mbps to 1000Mbps Gigabit Ethernet. I need to buy a new switch but I have 2 questions: - Can cat5 cabling do the job or do I need cat6? - All the Gigabit NIC's I've seen have 64bit PCI interface. I don't have 64bit pci's in my motherboard. What am I suppose to do? Just want to have those 2 things cleare before buying the wrong stuff.
