2nd 7970 or 3 monitors first?

Well let me help you out there since I have both.

Now, let me ask you first are the 3 monitors you intend to purchase going to be 3d or 120hz monitors?

The only reason I ask is due to the 3d on 3 screens requiring at least 3 displayport outputs on a card.

If you are not doing that then do not worry.

I'd still go with the 3 monitors first since the games you mentioned aren't necessarily too demanding compared to other games, don't get me wrong though it's due to the fact that the 7970 is a powerful card. If you had something like a 7750 I'd say they are pretty demanding for you then on 3 screens.

I feel that the result of 3 screens is much more enjoyable now since you can as always tone down the settings in whatever you like and still play on 3 screens no-matter the game with that card.

Also, I really doubt you'd need the second card with those games. I've played Guild Wars 2 and I'd say you could max everything even with eyefinity and play fine. Now, if you go into say Crysis 2 you would not want to expect the same result.

If you need any further help let me know, but have fun gaming on 3 screens! I will always go out on a limb to play on the 3 screens of mine whenever I can.

No it will not be 3d monitors, the refresh rate will most likely be a regular 60hz refresh unless more then that should be something I need to look into.

FFXIV 2.0 is releasing soon, and I really dont know when I can afford my second card again if I go with the monitors. I just do not want to experience a loss in power even though I do realize how much power my card alone has.

I have not played FFXIV (well, more correctly I played for exactly 1 minute before I got booted out of the beta and then could not log on again so I decided to not play). So I could not necessarily tell you one way or another on FFXIV 2.0, but I don't see it using that much power.

Look at it this way, if you go with two cards I can almost guarantee you will not use nearly that much power. If you go with three screens and the game is too demanding you can always use your 1 monitor.

Also, you really should look into 120hz, I only say so due to the fact I also use it. I swear that I will never go back to a 60hz panel, the smoothness is too worth it for me. Even if you just get 1 monitor due to funding, I'd almost say 120hz is better to have. It's hard to describe in words as well, but after using it you'll notice the difference (think back to CRT smoothness).
