Taka, I really appreciate this information! I do have Displayport cable and can connect the card and Asus VG248QE both via the DP cable, somehow on the Nvidia control panel in Windows 10, I do not have an option of choosing "120HZ" or "144Hz", I only have option choosing "60Hz" or below, which sounds weird to me. Windows 10 should make things easier not harder. If CentOS 6 works then Windows 10 should work, I guess I have to go back to Windows 7 if needed, but as I already ordered the DP to DVI active cable, I'll test this cable first and update CCP4bb later.
