what do i have to gain if i switch from cat5 to cat5eFrom lanshack.com:

Category 5 Cable Category 5e cable is an enhanced version of Category 5 that ADHERES to more stringent standards (see comparison chart below). It is capable of transmitting data at speeds of up to 1000 Mbps (1 Gigabit per second). Cat5 is a basic cable standard for 10/100 ethernet. Cat5e is enhanced with FireWire to give Gigabit (1000MB/s) speeds. If you use Cat6, the cable is thicker for even faster speeds up to 10,000 MB/s but it can still support 10/100/1000.
I only have a 10/100 network at home but will upgrade to gigabit.So it seem like it's time to upgrade my network sys at home soon,thanks for the reply. But i don't know if i should go cat5e or cat6 . i dont want to go to cat5e than a few later years have to go to cat6, it's up to how much i want to spend.Go with Cat6.Although what neelchauhan STATES is very true. We must remember that our speed to/from the internet is depend on the ISP Provider. LET's said for argument that if a ISP Provider can provide the max download/upload speeds (which is usually not the case), CAT5E will be more then enough. Once again the ISP Provider will furnish u with a modem to meet their speed requirements. Where CAT 6 truly might come in handy is if u use it in your intranet (home network). This means switching all from 10/100 Ethernet to Gigabyte hardware. CAT 6 is made for massive movement of data like very large file (CAD, video,etc) and Data Base. The typical home user would get very little if any advantage from CAT6.
