i want to buy a pc which connects permanently to a videowall with 9 full-hd monitors. right now i tested it with one with one nvidia gtx 1080 – i have 3 matrox tripleheads to go dp editions connected to its 3 dp outs and 9 dp cables to the screens. That works fine, but my question is if i could improve that setup if i use a pc with 2 gtx 1080 inbuilt (nvidia sli) – can one instance of max 64bit make use of both at the same time? If yes, could i also get rid of the matrox devices, since every graphic card has 5 outputs (3 x dp, 1 x dvi, 1 x hdmi) – so can i connect the 9 screens + 1 control monitor to the resulting 10 outputs directly? Anybody has experience with such a setup? Or what do you think would be the best graphics solution on pc at this time in general?

Max 32bit had some limitations of RAM use – is the same true for Max 64 bit?

+ For videoplayback i guess it is still best to have two ssds – one with the system, one with the video files – right?

nvidia-sli-possible-with-jitter-what-about-ram-limitation-2ssds-for-vids

I've never used multiple gfx cards but I remember reading that 1) multiple cards in SLI configuration are not supported by Jitter and 2) multiple cards (non-SLI) can be used but as discrete rendering units. So run 1 rendering context on 1 card, and another on the 2nd. What I remember reading is that sharing 1 context on both cards will deteriorate performance. You select the card by placing it's rendering window on the outputs (HDMI/VGA/DP...) of that card.

If I'd build a super powered PC now I'd go for the fastest i7 CPU and GTX 10-series GPU I can afford. 64bit Max/Jitter has better openGL performance, and you can use more RAM if I'm not mistaken. I guess 2 SSD's could speed up things but I'd test first whether running of 1 SSD really is a bottleneck.

thanks for all that information.

Nvidia Sli possible with Jitter / what about Ram limitation / 2ssds for vids?
