Cost is NOT really an issue. I can buy two additional 19" monitors with good specs and good reviews for maybe another 2-300 dollars. That's not a lot comparatively. Furthermore, the eye sees more horizontally than vertically, and adding two monitors to my peripheral vision is going to do a lot more than adding a few inches to my vertical vision for about the same price, as we all know (and apparently claim) prices go up exponentially with monitor size.
If you read around, you'd see that this feature is clearly for older games where the new 58xx series is seriously overpowered for the graphical horsepower they require.
The screen borders become invisible if you are adding periphery space around the central monitor. Try it; it is a well known, researched fact that the more you stare at one thing, the more it appears to disappear from your vision. Your eye is much more sensitive to dynamic objects as opposed to static objects.
There should not be any driver issues. Again, if you read, you would have known that the whole idea is to treat the setup of monitors as a single monitor, not like individual entities like Windows traditionally (?) handles them. Thus, when you select a resolution in game (they even showed screenshots of eyefinity resolutions in Crysis) it appears as one giant resolution.
Who says you have to sit far away? If I'm adding monitors to expand my periphery I will still be sitting at the exact same distance, but the 'dead space' that was there before will now be filled with information I can pick up on a subconscious level.
Eyefinity is definitely a nice feature and if it continues to be passed on to future generations, I might consider a multimonitor setup.
Also, to those people who complain the other monitors would suffer from poor viewing angle, all I have to say is: adjust them until they are OK (e.g. angle them). The rationale behind this, especially for FPS, is that the game probably (I'm not sure?) renders what you see based upon a circle field of view. Setting >100 degree FOV ingame (Q3, Source games) and actually having monitors capable of displaying that without the crazy distortion you see in a planar panel would be ... impressive.
They don't have multimonitor setup. After this card is released, that number may increase significantly.
Your second sentence makes no logical sense.
Of course it will take a performance hit. But if it remains above a certain threshold, you will most likely not be able to feel it unless it dips under 30 in chaotic situations.
Again, you should have read before you said anything; the monitors are merged into one large resolution, instead of being split and handled separately.
The 5870 was also running Left 4 Dead, Flight Sims, and I assume should be able to run RTS' with ease.
