From my understanding you NEED SLI mobos to run video cards (i think only nvda or normally nvda) that have two or more output regardless of its use.
example: if you have a nil sli mobo and you have a video card that has two out puts, therefor 2 max monitor use, you can only use one monitor (if its compatible)
Here is my 2 most cost efficient options.
1) upgrade the mobo to the one above, keep my current vid card and get another dual nvda card. and get two monitors for a max of 4 (but get 2 24"+ to compensate for lack of max monitors)
2) upgrade mobo, i think a crossfire, to get 2 cost efficient amd5000 series (which have 3 outputs, 2x3 = 6 screens) and possibly need to upgrade ram/power supply?
Obviously option 2 would leave me with my current vid card useless for a while, sitting around and such. and this route will be twice as expensive as option 1, however, will be half as expensive to get a bran new system all together.
Hard decisions here
