Multi Monitor - SLI 670/680 Question

post #1 of 3
Thread Starter 
Been out of the game for a while, bought a GTX 670 FTW a few months back just to stay up to date.

I have looked for an answer to this, but can't see to find anything definitive enough to convince me to make a purchase of a 2nd GPU.

I see that this card can support 3 & 4 display setups on its own, which was previously reserved for SLI setups in the 4xx/5xx series cards. Does this apply to independent displays? (meaning no surround) or is it just for surround (spanned resolution setups?) I don't have the adapters I would need to rig this up at home to test, which is why I am asking here.

Also, does the same apply for SLI ?

I do not use surround in any way and mainly will use this for multi boxing eve online. I put one client on each display and in windowed mode move to and from them. My goal would be to maintain my "accessory" display setup where I have a primary and two accessory monitors, but still have the SLI pair working together to render the one, two, or three clients that may be running at a given time.

I know that I could always disable SLI, but I would prefer to load balance the three clients over the two GPUs instead of 2 / 1 AND I would like to have SLI enabled all the time for when I play SC2/Dota/PS2 and just use a single display.

I'm not exactly sure what you are asking, but the 670/680 can support up to 4 displays, surround or not. If you don't need the power there is no reason to get another 670.

Yea everything is so "surround" oriented these days. Gotta thank nvidia for making their hardware difficult.

I do need the power. I am running 3 clients at 1920x1200 at max settings on three separate displays. I cap it at 60 fps now per client and it works, but I am running two displays on my 670 and one display on a 460.

My goal is to have SLI 670s handle all of the video processing for the three displays.

I need to know if I can run three independent displays off of SLI 670s without having to enable surround for the spanned resolution. With the prior models 400/500 series cards, if you had SLI and wanted an accessory display, you would need to buy a third video card of a different type than the other two. Otherwise, the only way to run 3 displays off of SLI was 2D surround, which eliminates your ability to run independent displays.

I want to know if that is changed now that Nvidia supports 4 displays on a single card... is that also true of SLI ?
