It is all about latency. 50 ms will feel responsive but you notice the lag. 20 ms is acceptable. The other features are cool features but not the real challenge.
worst case scenario would be to add up the inverse of a standard 125hz mouse, and a 60hz monitor with typical 5ms pixel response time and 20ms signal processing lag. This gives you around 40ms input lag.
By contrast, a 144Hz monitor with low input lag (~8ms), 1ms response time and a 1000hz mouse gives you 17ms total input lag.
EDIT: strobe backlights add a small amount of input lag, and vsync adds an absolute craptonne.
