Do I need one for my custom build? b/c I don't want to make it wireless there is already a modem in another room and I can't connected all the way to my room so. Would I need this below or not? plus I like to use and take advantage of the Gigabit Ethernet my motherboard has

sorry guys ment to show you these routers instead my bad, but however the only things that are going to be connected wired will be my PC, PS3, and maybe a fax. however I like to use the gigabit opt that I have on my MOBO, I don't think the PS3 supports it but could I still use this router I"m going to show you guys or it's just a waste of my $$$ to buy and something I really don't need thanks!!
