    I am debating returning one of my HD7970s, been getting alot of visual fragments when playing Dota 2 in Xfire. After perusing the boards it seems this game just really doesn't like XFire.

    1. Are there alot of games that don't like Xfire. Is there a list somewhere?

    2. Or is disabling the Crossfire option for games without a profile(as you can do in Catalyst) just a good idea?

    I'd just get rid of a card. I'm running at your resolution with a single 7970 just fine. CrossFire just isn't very good.

    Why isn't it very good, I've not had a single issue all year. Id just accept this one game doesn't like xfire and disable it during that one game .
    In general xfire can be iffy whe a new generation first comes out and upon a new games release .
    I have 2x 5870/50 and they matured well with no issues these days.

    Yeah, that's not a 7-series card. 5-series Crossfire and 6-series, yes, very mature, and works well. 7-series still needs driver adjustments, the whole fact that 7950 = 7970 when at same clockspeed says that perhaps 7970 isn't being fully utilized, and more performance is possible there, even.


    I just tested 5850 Crossfire, and I see why you feel how you do.


    6-series Crossfire, adding a card nearly gave 95% performance boost. 7-series, it's 60-90%.

    Plus, there's that whole memory management thing. If you peruse OpenCL documentation, 7-series cards only allocate 2048 MB of 3072 MB, even. Makes me wonder if in DirectX, do they do the same, and are really only using 2 GB of ram?

    Anyway, adding a second card just further complicates things right now. I will give AMD about 4 more months before I expect a really good driver. If they fail to deliver in that time frame, I'm leave AMD behind, and selling off all my cards.

    Ill give you all of that , a reasonable and fair statement I have not been a xfire on new cards user since 3870s so im clearly blessed with the luck of being poor alas.

    1) Sell both
    2) Buy Titan
    3) Start a TPU Titan Clubhouse.

    What were those 5850s getting as far as utilization?

    70-85%. Not utilization, but in performance boost from second card. Utilization readings are crap in this regard, IMHO.

    Wow that's not to bad at all! I know the 6xxx series was better but I never thought I would hear the 5xxx series hit 85%.

    Exactly how I feel, I usually get 30 - 40 % more fps or score on most occasions

    So going to a 670 was a better move than getting other 5850 you think? I mean I'm happy with it but now I'm wondering if I could have got better FPS in crossfire despite the issues.
