Hi all,

So before any remarks, my use for graphics cards are video editing, professional 3d applications, gaming, benchmarks, adobe creative suite (running up to 3 programs at a time) on 4-6 monitors, so I need high-end graphics performance. So my question is this: Should I get 2xGTX 770's in SLI or a single GTX 780Ti in SLI? I will be water cooling them with twin 360mm radiators so cooling will not be a problem, my power supply is rated at 1000 watts, so power and heat will not be issues. The cost of either setup is ~800 USD, but I am asking which one would be better suited for my use. The GTX 780Ti seems to have a higher core count, but GTX 770's in SLI will have 2x more Video memory and twin GPU's seem to render faster than a single GPU, but I need help clarifying.

Thank you,

Nuclear101

My take is to avoid dual cards if a single card will do the job.

The vram on two GTX770 cards is not additive so the 3gb of the GTX780ti is actually better.
If it is the GTX780ti black edition, you get 6gb vram.

I don't think you meant GTX780ti in SLI, but using a single card.
One problem might be how to attach 6 monitors.
Most single cards will not attach 6 monitors.

When gaming on a single monitor, the extra side monitors add very little load.

Or... perhaps something like 3 2560 x 1600 monitors might be very good.
It will have about the same number of pixels as 6 1080P monitors.

If you were to try to drive all 3 for one game, then you might indeed want the sli GTX780ti cards.

An interesting approach to extra display real estate...

An interesting approach to extra display real estate might be a 4k monitor like the seiki 50" monitor.
It is no good for gaming since it only refreshes at 30hz.
You could possibly use the 3 motherboard integrated adapters to do it, or just add in a second cheap graphics card.

Incorrect supposition - SLI/X-fire does not share the video memory, it will only recognize the video VRAM from a single card. The combination of the GPUs doesn't give you a 1:1 ratio of power, it's more like an additional 50%. 3D modeling is video ram intensive so the 4GB 770 is probably the better option for day to day use on that setup. If it were my duckets, I would find a way to get a first-gen Titan. 6GB of video memory would be killer for your purposes and it's got the muscle to push to those displays. Beware - it's going to be difficult to get any single card to push more than 4 displays (even the eyefinity cards that were meant for that purpose). Nothing is impossible, but it's not going to be as clean as you'd like I am sure. If you're wanting to push 1080p or high to 4 or more displays and do 3D modeling I would go with (2) Titans in SLI (my wallet would probably punch me in the junk for even thinking that if it could). That's not practical but if that's what you're wanting to do and to do it well, that's honestly what you'll need.

EVGA Titan Black Hydro Copper series. Or get 2x GTX 780/780ti. GTX 770 won't give you what you need. I have a regular 780 and it clocks out of the box to what the 780ti lists as its boost clock. So either card(s) are great. I thought about going with 770's but I went with a 780 to test the waters. I am in no way, shape or disappointed with the 780. It tears everything to shreds.

I gather you're talking about 1080 videos. You don't even need that much firepower. And I've got no idea why you'd want so many monitors. Usually 2 is enough for editing. Hardware acceleration uses GPU power to help. But it's CPU power that really does the job. That's where your money needs to be. One 770 would be enough for 1080 games.
