The key reason to run higher FPS is the render time. At 1000FPS, the server is rendering one frame every 1 millisecond (ms). This means that the worst-case adder to the player ping is only 1ms, IE: the player gets more accurate data and can get it more often.
At 300FPS it's only 3ms which is perfectly acceptable, but at 100FPS it's 10ms, which is a significant percentage of a 100 ping (10%). A player with a 100 ping would actually be getting 110ms response time from the server. Many AMD systems will only run 60FPS without the ping booster which is 17ms.
This is still not too significant but it can change the feel and response time of your server for players.
Without the FPS Boost your server will use significantly less CPU but accuracy may suffer.
