By increasing FOV and going to a bigger screen and resolution all at the same time it's like keeping the exact same experience as before, plus the added area on the periphery - so it doesn't hurt to be able to see more on your screen. Then you will feel perfectly comfortable keeping the big ass monitor close to you. In strategy/3rd person etc. games you can see more with less moving around and in 1st person games you also need less looking around and can detect enemies on the sides, above and below faster. With vehicles it's even more important, because to look around you usually have to move a turret or even the whole vehicle (aircraft for example). If you try to go from high FOV to normal you realize how limited normal FOV is - its like having zoom on all the time and you want to zoom out to be able to see things around you. The only discomfort comes if you have to look at HUD often, especially if you had the smart idea of using a 16:9 display for games (dunno about new games - I guess they design them for wide screens somehow, like automatically increasing FOV to keep the vertical angle constant, which is the only sane thing to do). But HUD in many games is not "heads-up" anyway. Proper heads-up display is what you need in any case.
