How will Two Titans stack up to my 4-way 670 4GB

So I've been thinking about getting some Titans for gaming at 7680x1600.
Currently I run 4-way 670 4GB cards.

I'm wondering if 2-way Titan's will be enough for the 7680x1600 gaming session (without AA being turned all the way up). Is this possible? Or will I need a 3rd or 4th Titan for smooth gameplay?

And I should qualify it and say that I'm not looking to be able to crank crysis 3 up to max AA and setting or Metro, but other DX11 titles possibly.

Well and now that I think about it, would 780's be a better middle ground for the memory bandwidth?

I'm sure the Titan's will stack up pretty well but not because its more power, only because 4-way SLI just doesn't work nearly as well as 2-way SLI. I would imagine you would get a much more consistent experience from two Titan's than four 670's.

are you really seeing slowdown with 4 670s?
Titan's are much faster, but I'd be surprised if 2 of them is noticeably faster than your 4 cards.
780's might be more cost effective, but you might notice the loss of 1GB of memory.

It's been shown time and time again that 4 cards in SLI/Xfire don't provide a great gaming experience. Especially at lower framerates which you're experiencing at that resolution. Two Titans would likely provide a VASTLY superior gaming experience, if not framerate.

Ditch the 4-way and simplify with either 2-way or 3-way with 780/Titan.

I got 3 780's. I like them so far. I notice that I've got more performance with the new cards but at my resolution it looks like the vram may be holding me back on certain games (skyrim and tomb raider). I may just go back to gaming on my 120hz 1080p monitor. I like that smoothness anyway.

Are you actually watching the the vram go up to 3GB and experiencing stuttering in Skyrim and Tomb Raider? I'm curious because I've suspected 3GB wasn't going to be enough for me at 3 x 30" but I haven't actually seen anything I've run go higher than about 2800MB.

Before I got my 4GB 680s it was obvious in my games when my old 580s would hit their 1.5GB wall....the stuttering was horrible.

Tomb raider not so much but Skyrim definitely. Both games ramp up to 3gb pretty quickly.

I think you should stay where you're at on GPUs. You have enough GPUs and more VRAM than I do. I can peg out VRAM on my 780s pushing 3x 2560x1440 in a few games and reduce my monster rig to a slideshow

FC3
Crysis3
Bioshock Infinite

So far that's my list. I can't run AA in FC3 with everything at Ultra. Crysis is a bitch smack no matter what you do pushing this many pixels. Bioshock Infinite, like FC3 is limited really only in AA usage with 3GB. Technically 3GBB being 3072MB, but anything over 3GB really starts to stutter, despite what FRAPS and eVGA Precision report.

Edit: I'm running the following: i7 3770k @ 4.8, 32gb ram, Samsung 840 pro 512gb, evga nex1500 classified, asus maximus v extreme, quad 780 (tri-sli+physx), surround asus pb278q

Thanks. I figured. My bank account needs to start worrying the next time up late and do a search for "nvidia titan" on a shopping site.
