Two Nvidia 770's or Single 780 for 3-monitor surround...

I have been racking my brain to decide between two 770's in sli or a single 780 for a 3-monitor surround setup but I can't decide. I would definitely love to have the 780 but will it be outshined by two 770's? Does anyone know of any benchmarks for 3 monitor setups comparing the two? Any help would be greatly appreciated :) .

Two GTX 770 2 GB will demolish a GTX 780 3 GB, if the resolution is right.

However when the resolution increases the demand of VRAM increases as well and when you have two GPUs with 2 GB of VRAM each only 2 GB can be utilized.

My GTX 670 uses almost 2 GB of VRAM in some titles at a single 1080p monitor.

Therefore the VRAM will be quite a bottleneck if you're going 2-way SLI GTX 770 2 GB. I would either get two GTX 770 4 GB or a single GTX 780 and have the option to add another GTX 780 later on. :)

As I just wrote you can see in some titles that the VRAM is the bottleneck as adding another GTX 770 doesn't even come close to 2x the performance. However here is optimization also a big factor, mind that. :)

Those are actually the cards I've been debating. I've been stuck on them for a while but I am going to have a resolution of 3240x1920 in surround. With all these suggestions for more vram I'm considering the Gigabyte GTX 770 Windforcex3 4gb cards in sli. Any thoughts?

I would go with the 780 because you will not have to bother with wonky multi-GPU drivers. Some games they work fine but some games you will not see the improvement or it will be choppy. Plus in the future you can sli the 780, on top of that the 780 runs a newer architecture than the 770.

The general rule of thumb is to get the best single GPU you can, it cuts down on headaches and leaves you open to a multiple gpu setup in the future.

What are you expecting from framerates? A single 780 in BF3 at your resolution on ultra should hang out in the middle-high 30's given the performance of the Titan at a slightly higher resolution here: http://www.tomshardware.com/reviews/geforce-gtx-titan-p...

If you want closer to 60, can run the SLI 770s or turn down eye candy on the 780.

I was actually hoping for closer to 60. SLI 770's sounds like the way to go.

If you are going to be running those resolutions then you are correct. The 4GB Gigabyte 770's http://amzn.to/16OAqkj are the way to go. Gigabyte is a great brand also.

AMD is better than NVIDIA in multi monitor support.A lot of people say this but i can't say from my experience.

Unfortunately AMD isn't doing so hot when it comes to multi-GPU drivers which is usually the setup most people run with high resolution gaming.

Unfortunately the stutter on crossfire negates any advantage they might have.
