Do I need it, OR do I just want it?...

[HalfBlindProphet]

Soooo, I was on the forums a little while ago asking about multi resolution displays. In the subsequent time I have slowly been upgrading my 3 monitors to all 42.5in 4K screens. Specifically, I just purchased the third one last night and Amazon will be winging it to my location as soon as they wake up Monday morning. SO here's the BIG question: Here are my specs, 

CPU
    Intel Core i7 6850K @ 3.60GHz  
    Broadwell-E/EP 14nm Technology
RAM
    32.0GB Corsair Vengeance LPX @ 1066MHz (15-15-15-36)
Motherboard
    Gigabyte Technology Co. Ltd. X99-Phoenix SLI-CF (SOCKET 0)   
Graphics
    4095MB NVIDIA GeForce GTX 1070 (EVGA)

I run lightroom and other photo editing software as my profession. Once I get the third 42.5in 4K monitor, do I need to add another GTX 1070 to my board and SLI them together?

If you dont run games there is no need to.

1070 should have atleast 4 digital outputs, which support 4k.

I don't think it's a requirement, but it'll probably be nicer to avoid triple 4K on a single 1070.

You dont "need" it but i would only connect 1 4K monitor to the 1070 to use as the main display and then use a "display GPU" like a gt1030 or RX550 to power the rest of the displays.

 

The 1070 will then only be religated to work and the lesser one to displayout

If the 1070 handles the job now, it will do just fine with the 3 4K displays as it does have 3 Displayport outputs. If it doesnt, dont upgrade yet.

What for? He's not gaming, he seems to be doing photo editing.

Just have the one 1070, another one won't be useful.

How tf do you have a 4gb gtx 1070? Those don't even exist. did you mean a 970 or a 1070 with 8gb?

he's copying all that from Speecy, known to read half the VRAM regardless of systems.

interesting.

If you hardware-render, you should get a 2nd one if supported. if not, just sell yours and buy the next gen 70 or 80.
