Just like what is said above, all 3 monitors plug into the top card, and then you connect the 3 cards via crossfire bridges. Since you have said nothing about water cooling, also keep in mind these 3 cards sandwiched together are going to be quite toasty and loud.

You may want to buy one of those 'SpotCool' things. They can be manouvered to any part of teh case and can be very usful in CFx situations to blow air in/out

Even without having this in crossfire? Just one card plugged into each slot and one monitor to each card where this is no crossfire bridge at all?

Is it not possible to do this? Forgive if me I am wrong here, just thought I used to do this on old AGP/PCI cards. It's been a while since I have a had a new computer. tongue.gif

On the subject of watercooling if I am running 3x cards they would almost definitely need their own loop right?

I had thought about doing a watercooling loops for the cpu and a watercooling loop for the cards. Although temporarily was just going to do a corsair h100i for the cpu.

Cards do not "need" their own loop. you can put them in the CPU loop, just make sure you have enough radiator to back it up. atleast 4 x 120mm worth of rads.

They have to be crossfired, and you have to plug monitors into one card.

It defeats the point of having 3 panels or having 2/3 79xx cards if you don't use them in crossfire. The point of crossfire is to combine multiple cards into one logical card. Eyefinity takes your three panels and again doing the same as crossfire, makes them into one large logical panel. If you don't use them how they were intended there's no point to any of this.

Don't mean to be thick here. I understand that if I am running one game at one time the 3x card would be acting as one card that runs the game very well whether its on one screen or 3x screen with eyefinity. I get that.

But if I did have 3x 7950s, not crossfired. I ran a monitor to each card. And I ran multiple clients of EVE (or any game) on each monitor, lets say 3x instances on each monitor. In this situation would it not be better to have them seperate? Or does it just not work this way and I am imagining things. Or maybe it does work that way, but eitherway 3x crossfired with all monitors to one card will run the 3x instances per monitor better? My assumption was each gfx card would handle each monitors load allowing 3gb of ram for each monitor. (Assumption keyword)

Honestly that is my current main use of this system and the ability to play things like Farcry / Crysis is just a bonus and in the times I am playing it I could put them into crossfire to enjoy them that way.

If I have this completely wrong I apologize, and my memory is dated and failing me.

Ok, what you are asking about now is multiboxing, running three instances of whatver MMO. And in that context using it how you're suggesting is the right way for multiboxing.

Alright I feel a little less crazy now.

So in the instance I am multiboxing (which I usually am) the 3x 7950s still the better choice over 2x 7970s?

And when I go to play crysis or something of the like I can always just crossfire them.

EDIT: Maybe better question is 3x 7950s or 2x 7970s with a 3rd 7970 added on later, or is it even worth it $$ wise to run 3x 7970 vs the 7950. Would probably allow for future 1440p gaming? (I am really bad with keeping on budget haha)

My advice if you are planning to play on 3 monitors (5760x1080), I would start with 2 7970s or 7950s, and then add a 3rd if you are not happy with the settings you are playing on.
