Correct Monitor Refresh Rate?

[lawrence.petrykanyn at sympatico.ca]

Hi,

I just successfully installed Gnome2.  When I switched my screen resolution 
to 1280x1024, I had the option of using 60Hz or 87 Hz as a refresh rate.  I 
chose 60Hz because the monitor manufacturer's web site said that 1280x1024 
@65Hz was supported. Was this the best decision?

My monitor is a Samsung Syncmaster 763MB.

Thank you,
Larry
