Hi, I have recently purchased the Samsung's 173T, and currently I am setting it to 1280x1024 @ 60 refresh rate. However, there's also a 70 fresh rate availabe at that resolution. My question is that does it matter between 60 & 70 refresh rate for a LCD?? Is there a big difference for gaming?? since refresh rate is supposely to be important for CRT monitors, but I am not too sure about if it's an important factor for LCD.
