i have a computer which is very laggy with games. i just bought a new gaming desktop for everything. i need to move EVERYTHING from the slower computer to the new one. both computers are running windows 7. i am planning on using a crossover cable. is this possible? do i need 3rd party software? do the computers have to be plugged up to a router or can they be directly connected through the RJ45 port (ethernet)? is there a faster way without using removable media? please send all info possible. thanks!
