Yes the cordless keyboards can cause gaming problems. They don't send information quick enough to keep up with the average gamer under heavy fire. The biggest cordless bottleneck though is if you're using a cordless mouse as well. They only refresh 30 to 40 times/sec, and if there is a signal break they can take 1 or 2 seconds to reconnect. A good USB gaming mouse will update 120 to 150 times / second and run you maybe $50 (Canadian I don't know about American prices). If your going to do a lot of gaming, kill the cordless.
