There is not much LCDs able to provide high quality (according to my eyes and my mind, its not same for other people). At least not the small ones, with a few unknown exclusions. But i dont know any, as good as any LCD got some weakness which my eyes can see and they are unnatural at colors (white detail usualy good, but black detail is a mess). But depends on the game, i play EVEonline and a Plasma totaly owns at all those dark space... but i like almost any space game, so i have high benefit from black detail performance. My 2, actually 3 most favorite games is RPG, Strategy (such as CIV) and space shooters, thats where i need "true" performance.
We may in some future see some superior screens such as OLED/PLED and how they called. Currently, Plasma is the only screen im satisfied with. Laser TV is another option, but never been released in europe. I dont trust those computer baby monitors to much, its better to have one single screen with outstanding quality, than a lake of small ones with average quality.
Eyefinity might be fun, but when to close its impossible to see the whole screen at once. So the tech works by providing lot of unnecessary room which cant always be seen. Yes thats reality (no one can see entire reality) however, its not practical because i always need to have my character in viewing angle, else im gonna die. So a screen perfectly shaped to my viewing angle is more practical for gaming and movies, so i dont miss certain elements. A single screen can provide the perfect viewing angle. Of course, a character is always in viewing angle, but left and right side of me is kinda a underused space with elements i dont actually have gaming benefit from, its just some enhanced area with stuff i rarely see. Eyefinity is fun, never told different, but its not to practical i feel. If i go eyefinity, i would try to attach several huge TV to each others.. but thats just not realistic because to expensive (im not "rich" at money, but prehaps rich at brainpower
)
What will change in the future for me? I will use some sort of OLED (probably up to 60-100 inch size) with 4k resolution for gaming, thats the advancement we will meet someday in future. Currently im satisfied the most with a single 42-60 inch 1080P Plasma screen.
