This box is getting troublesome and it's about time to replace it.
I do play RTS and MMORPG games but not FPS games.
I am currently running three monitors on two video cards.
I'm looking for something good but definitely not bleeding edge.
What should I be looking for?
ATI cards featuring "Eyefinity", can drive at least three monitors.

Nvidia announced something like that, but I think it still takes
two cards.

A review of what Nvidia is offering, from June 2010.

With the ATI approach, you may need to buy one of these. A DisplayPort
to DVI adapter.

So it looks like ATI can do it (drive three monitors) with one video card,
while Nvidia needs two (and a software approach to driving three monitors).
But the ATI may need help from an active dongle, to convert from one
display output type, to another.

The video card should be powerful enough, to drive three monitors
at a decent frame rate. I have no idea what a MMORPG takes - it
probably still needs 3D rendering power, and you likely wouldn't be
happy, if the monitors had lag between them or with respect to
gameplay.

This 5850 has a good collection of connectors on it. Including
two DVI, a DisplayPort and an HDMI. In principle, you can use
an HDMI to DVI passive dongle, but I don't know if that
satisfies the "clock signal" requirement described in the
Anandtech article (necessary to make three monitors work).
My guess would be, you'd use two DVI, plus a DisplayPort to DVI-D
active dongle, to make a third display channel, and that would allow
you to drive three DVI monitors. DVI-D means there are no VGA signals
coming from the active adapter. Cheap LCDs usually have DVI inputs,
so DVI is the most likely input type to be shared by all the
monitors.

And this 5850 has two cooling fans, with the objective of
lower fan noise by being able to run them a bit slower.

The customer feedback reviews are a good source of technical info
on running the cards.
"Multi-Monitor flickering is not Gigabyte specific and is due to the
lower GPU/Memory Clock rates when not making 3d calls. You can use
a program called 'ATI Tray Tools' to force constant clocks at all
times which will remove the flickering when using multiple monitors.
I have 3 monitors with no flickering issues in Eyefinity and
non-Eyefinity modes.
On another note, if you want to use Eyefinity, you need to create
a display group. In the 'advanced view' catalyst control center,
navigate to 'Desktops & Displays.' You will find an option to
create a display group by clicking on the down-facing black arrow
next to the virtual display and navigating to
'Display Group' -> 'Create Group.' Now, your computer will think
you have a single large screen display instead of a multiple-monitor
setup."
So if you had a card like that, you could either run it in a game,
as three separate displays, or as one panoramic 5760 x 1080 display.
One other detail, is the length of the video card. You'll need
a computer case, with sufficient room for a long card. Some
of these cards now, are 10" long. You'll need to go to the
manufacturer's site, and get a length spec.
There are plenty of other articles for judging how to put together
a system. What you're looking for, is graphics performance of 30FPS
minimum, if you can get it at a decent price.
