@animexlife Don't worry! You can use your old monitor with no problems. :smiley:
G-Sync (nVidia) and FreeSync (AMD) are features some monitors have, that automatically synchronises the framerate the graphics card spits out with the monitor's refresh rate. This is to avoid "tearing" and "stuttering". My monitor doesn't have this feature and I don't have any problems at all.
Just turn Vertical Sync on in the nVidia settings and you're good. :smile:
On my computer the Vertical Sync setting in the NVIDIA Control Panel is under "Manage 3D settings".
With V-sync on the graphics card doesn't have to work as hard, so it will be cooler, quieter and draw less power. :smile:
