I'm planning on adding a 2nd AMD 5770 (it's free and it works so I'm not buying another anythting right now) to a mac pro 5,1 which has two 16x PCI slots. While I'm aware the cards will dumb down to 8x speed I'm curuous to know should I run these crossfire or stand alone for DS 4.8 on a two monitor setup? I'm looking for flexability with the GUI and I'm rendering with Lux so I don't need GPU render since the system will max 2GB VRAM but has 64GB system RAM.

 

Does the 2010 MacPro even support CrossFire? Anyone try this? Any benefits to one setup and not the other and not the other?

    I'm not certain what advantage you would get by using crossfire, Stratdragon, unless you are gaming on the machine. It will certainly boost your fps, but aside from animation playback, I can't think of a benefit for most 3D work. As for crossfire support on the MacPro, I can't say - the hardware itself should support it, but its hard to say what jiggery-pokery Apple may have done with drivers, BIOS and firmware. Some other MAC user may be able to say.

    I found Crossfire not was supported in the 2010 MacPro 5,1. 

    Now I have the joy of tying to match my win7 layout in Win 10, so I guess my next post is how can I just pull the layout file over and have everything where I put it!

    What do you mean by layout file, Stratdragon? Are we talking about Windows or DAZ Studio?
