Can someone recommend me a monitor around $120 - $170?

I have never had any problems with gloss or reflections

Refresh rate. Every monitor has a maximum FPS that they can display. If they're sent anything higher than that from your GPU, it will be invisible at best, and cause some framerate tearing at worst. 60Hz refresh equals a max visible fps of 60. 120Hz is 120fps, but also means 60fps 3D, if you're buying a monitor capable of outputting 3D movies.

Response time. This is how fast each physical monitor pixel can change what it's displaying. The faster this is, the less motion blur. Higher refresh rate monitors tend to have lower response time, but these are not directly correlated.

Screen size and resolution. Larger screens can cause neck strain if sitting too close, but are great for distant viewing. But consider how large you want the screen to be within your field of vision. Example, if you put an iPhone screen close enough to your face, it's the same size as a 32" screen. Therefore, screen size and resolution are both important. The perfect match will make it impossible to see where one pixel ends another begins, which is what Apple's Retina Display does. How far you sit from your screen will also affect this. If you can't tell if you're looking at a screen or a painting, you've reached or surpassed the limit of your own eyes, which may be better or worse than other people. Past this point, you can't see the resolution difference. In-store demonstrations can help you figure out what screen size is perfect for you, given the distance you sit from the screen.

Color depth. Things like how accurate the colors are on the screen, how vibrant they look. Also related is how pure the white and black color is. Some cheaper LCDs can't do real black, and instead display extremely dark red. Rare to see today.

If you intend to use a multi-monitor display, such as EyeFinity, you'll want the thinnest bezels possible. Or removable bezels, check forums for recommended models with easily removed bezels.

The descriptions of these should help you determine which of these is the most important to you, as it may differ from what I believe.

If you use Nvidia GPUs, consider waiting for G-Sync monitors. They are supposed to lower their refresh rate to exactly match the FPS output of the GPU, reducing incidence of noticeable FPS stutter and eliminate screen tearing.

EDIT: This info from Newegg.com should also be helpful.

Yeah, I saw that too.

I should have gotten it on Black Friday. :(
