Multiple Routers

Hello!
I have a Netgear WNDR3400v2 that connects to my cable modem. I then have a wire running to two computers, then a third running to a Linksys WRT54G. The Linksys is just used to split the connection to a gaming PC, Xbox 360, and PS3, its wireless capabilities are disabled. What I would like to know is if it would be better to keep it the way it is, or plug the PC into the cord so that it is connected directly into the Netgear and have the Xbox 360 and PS3 wireless and eliminate the Linksys.

Thanks in advance,
