If i get a gig ethernet switch and connect to the router would i not be still limited to router max?
The slowest link determines the speed.
LAN traffic, with the exception of DHCP, does not use the router so it does not determine speed. To prove it to yourself you could do an experiment. Plug the PCs into and Ethernet switch and the switch in turn to the router. Turn off the router PC to PC traffic will work just fine.
WAN traffic speed will be determined by the router, or more precisely the speed of your ISP connection since that is typically much slower then what the router is capable of.
