I'm planning on getting a third 6950 for my setup but wanted to ask a few questions before going through with it. Currently I have 2 x 6950's in x-fire pushing 3 monitors in portrait. Since I'm using a mini display port -> DVI I'm getting the screen tear issue on one of the monitors. I'm thinking of going to 3 GPU's and have them hooked up one monitor per card and ditch x-fire. This would eliminate the mini dp port adapter and hopefully remove the screen tear. I was also hoping that it would remove any x-fire issues from games. I know that the issues are generally addressed, but removing that from the equation all together seems a good idea to me. My only concern is, without x-fire, how does windows and games handle 3 GPU's? Will they all work fine or will windows or the game only see my primary GPU and use only it? I just want to make sure this will work before I drop another $250 on a card.

Eyefinity 100% of the time requires all displays out of a single card. Only NVIDIA Surround bridges ports on other cards. It's simply not an option for Eyefinity.

Well, that's mega gay. Thanks for the clarification though. What are my options to get rid of the annoying screen tear issues?

Your only option is to get a card with at least 3 identical parts. Eyefinity 6 cards or direct cu ii would be your best bet. Then run them in tri fire.

I do not think that the 6 series ATI cards supported Trifire...?? That doesn't mean you can't plug three in and run extra monitors off the extra card. I just think that you can't make a eyefinity group without all the plugs comming off one card.

really, the 6xxx series doesn't support trifire? i'd look into nvidia alternatives, but my mobo only supports crossfire, not sli. would a flex model card work for me? i've almost considered waiting for the 7xxx series..... which should be a performance upgrade, but i don't know if the 7xxx series will have issues with screen tear or not.

recommendations?

The 6xxx series does support Crossfire, and 3 and 4-card setups. Yes, all displays have to be connected to one card.
