I'm a total tech noob, but I just had one of my 6 year old monitors go south on me and I'm looking for a replacement.

Eve is my game of choice and has been for about 4 years.

So, would getting a 60 vs 120Hz monitor make a difference for Eve.

I do play some Counter Strike and some Skyrim type games as well.

getting a 120hz makes a huge differnce with moving windows outside in windows , and it games its magic :P

got a 144hz benq montor and i can tell you that your eye can detect more then 24 fps :P Cant even look at a 60hz monitor anymore, without seeing how choppy it is compared to 120+hz..

All i can say is get one :D

Just as a note, with vertical sync enabled, this will cause your GPU to work harder to produce more than the 60fps when synced to a 60Hz.
It will be trying to keep to 120fps, for 120Hz. This will cause it to work harder, and run hotter. You can of course sync to half the monitors refresh rate, but then you wouldn't be utilizing the monitor for its true potential.

Just a note, depending on what you currently have as your graphics card :)

Except in the case of double buffering with vsync on, your GPU renders frames asynchronously to the display, meaning GPU load is not even correlated with with your refresh rate.

The part of your videocard that dumps the framebuffer to the monitor will be working harder, but I can't see that being a significant portion of power draw, but I could be wrong.

This is of course not backed by my testing, but my understanding and 20+ years of working with computers, so I could be wrong or could have corner cases.

Err, correct me if I'm wrong, but when we moved away from CRT monitors refresh rate now means something completely different.

It now means each individual dot on your screen is capable of changing x times per second. - instead of a strip of your CRT screen changing x times a second.

so while it is true the eye cannot distinguish anything over 60hz (otherwise when looking at a CRT monitor it would be like looking at a strobe light) LCD/LED monitors do not apply in this sense.

long story short, higher refresh is better - but really high is not important. - not yet st least, unless you have a really big monitor
Another important thing to be aware of is that most video (and games) comes standard at a multiple of 60, so if your going to get a monitor with 60> make sure it is a multiple of 60 (120, 240, 600 etc.) - save you having to faff about changing settings or putting up with dodgy video playback

For the most part.

CRTs actually scanned the monitor phosphorescent surface with an electron beam, which means the pixels turned on and off. LCD pixels don't really turn on and off, but instead smoothly transition from one color to another really fast. This means no "strobe effect".

In real life, objects move smoothly through space while you watch them. As they move faster, they starts to get a motion blur that your brain can use to gauge the speed.

Now take a a 1080p monitor that is 1920 horizontal pixels and 60hz refresh.

If a fast moving object moves across your screen in 2 seconds, it must transverse 1920 pixels, but only has 120 frames to do so(60/sec). This means the object does not move smoothly through space, but instead jumps 16 pixels at a time. This makes it harder for your brain to track it.

While the brain only works around 24/30fps internally, visual queues from motion blur helps supply data. Either we need an algorithm that can correctly create identical motion blur, or we need a much higher refresh rate so we can supply lots of raw data and let the eyes create the motion blur.

The simplest way is to just have higher refresh rates with high FPS.

I am sure that there are other parts of the eyes and brain that can pick up other visual queues, but motion blur is one of the more noticed.

The best way is to just produce high FPS with high refresh. Back in my prime days of playing Quake Team Fortress on my 85hz monitor, getting over 100fps, I could instantly tell the different when I tried out my friend's 120hz monitor. I was playing noticeably better in close combat where lots of fast movement was happening.
