I have a MacBook Pro Retina, and I'm gaming a lot with bootcamp windows 8. I'm considering buying a external monitor for better gaming (might be a BenQ, has to be 120Hz). My questions:
- Does a 2nd monitor affect CPU performance?
- If I buy a good monitor, is there only the latency from the monitor, or is there also other latency? (Some monitors have latency of 1ms, 5ms, which is quite good, and not a problem, but if there's more latency because it isn't my primary screen or something, I need to reconsider).
EDIT: And, I've also heard people say that it's useless to connect a 120Hz monitor to a MacBook because the videocard is only able to handle 60Hz. Any confirmation? (Hopefully not)
