I'm getting hollow new computer and I cn afford buying up to 27" 1920X1080 monitor but I fear that my system can't play it as much as I want. I want about 40-50 FPS with small bit of AA. I have AMD FX-6300 , 8GB 1866 mhz , 1TB Cavair Black and 650 ti boost 2GB or 660 according to which monitor I will buy.
The Final questions:
1)Does 27" 1920X1080 monitor need stronger Graphics card than 23" 1920X1080 monitor?
2)27" 1080 monitor with 650 ti boost or 23" 1080 monitor with 660?
3) what is Wide Screen? and how does it differ? and Is their other types?
I feel like you are asking "What weighs more? A pound of feathers or a lb of lead?" The answer is that there is no difference, both are a pound. Just the same for the monitors; the amount of pixels are the same on both monitors. Obviously, the ones on the 27 inch would appear larger than the 23 inch. The monitor size is really more of a personal preference. If you want better gaming quality, then get a better video card regardless of the monitor size (if resolution is the same).
1) No. 1920x1080 has the same burden on the GPU regardless of the physical size of the monitor. If the monitor is a 5 inch 1920x1080 then it will be the same burden on the GPU as a 5 trillion inch 1920x1080 monitor.
2) Meh. Your preference. Do you want a larger screen? How far away from the screen will you be? The further you sit away from it, the more you'll want the 27". The physical size of your monitor is up to you and your individual situation. But 1920x1080 is the current 'standard' resolution and can be had cheap. I wouldn't get anything less than 1920x1080.
3) "Wide screen" refers to approximate aspect ratio. Aspect ratio is the ratio of the width of the screen in pixels by the height of the screen in pixels.
-In the old days we had "fullscreen" TVs and computer monitors (I use three fullscreen monitors myself). Fullscreen has an aspect ratio of 4:3. An example of a fullscreen monitor is a 1600x1200 resolution monitor. See how 4/3 = 1600/1200? That means it is four pixels wide for every three pixels tall.
-Widescreen monitors are the standard today. They usually either have an aspect ratio of 16:9 or 16:10. 1920x1080 is an example of 16:9. See how 16/9 = 1920/1080? That means it is 16 pixels wide for every 9 pixels tall.
