Frame times vs Frames per second

So I'm a bit confused between these two. I know that frame times(frame latency) is the time that gpu needs in order to send picture to the monitor(I hope that's right?). So what is really the recommended frame time so that we don't see any distortions in the image that's being produced by the monitor. I have a 60hz 5ms 1080p monitor and a r9 290. I can get 1080p@60 no problem but I can notice some distortions(stutters). I have an i5 4690k so it's not the cpu and 16 gb of ram, 650W gold PSU. I know that amd is quite famous for their high frame times. I can also see some screen tearing when I spin the camera but that's probably because of the ramdac. So my question is, how can I reduce my frame latency so I can reduce stuttering.
 
Solution
Frame time is the latency between the start of a render and swapping the buffer, while fps is the number of frames (buffer swaps) in a second. If you're an engineer, you can think of it as fps being frequency and frame time being phase. tearing occurs when there is a buffer swap midway though a buffer read from the monitor (which is always 60hz but continuously reading instead of discrete).

If you can turn on triple buffering or v-sync that should stop the tearing at the cost of frametime (higher for v-sync than triple buffering), or you can get a freesync monitor

Also, never use analog connections, use DP if possible, if not DVI or HDMI

144Hz monitors basically eliminate visible (plenty that isn't visible) tearing, and freesync monitors eliminate 100% of tearing.

Can you recommend me some great monitors that support freesync and have higher refresh rate(120-144hz). I would also like it to be IPS if possible and I have like $350(hard for IPS). I'm not really looking for 1440p monitors because 1080p is enough for me(I'm fine with 1080p up to 32 inches).
 


There is only one IPS 1080p freesync monitor and it's not sold in the US.
There's a few 144hz freesync TN ones though:
