If that's your primary setup, the Titan will go a long way from your 670s. Right now for triple monitor gaming, NV is not looking so hot. GTX690 is just 31% faster than a 7970GE and once you crank AA higher, it's game over for the entire GTX600 range:

As far as Crysis 3 goes, apparently the game has way superior graphics in single player. It's not even close from the pictures I've seen. As a result, the single player Very High hammers GPUs. You'll need 3 Titans just to max out Crysis 3 in single player on 3x 1080P screens because 1 Titan ~ GTX690! Here are new single player Crysis 3 benches with NV's latest 314.07 drivers.

Looks like Crytek did an excellent job as C3 scales very well with multi-core CPUs. FX8350 is beating i7 2600K! Although for 3 Titans I hope you have an i7 3930K @ 4.5-5.0ghz :)

AnandTech reported that their Titan card Boosted to 992mhz without any overclocking. Also, other reviewers said they managed to overclock the Titan to 1176mhz on the stock cooler.

$3K is a lot of dough. Not sure it's worth spending that much for a game with a campaign that's maybe 10 hours? You could always play it on High and save yourself $1K.

ATI was kinda a joke until AMD bought them.

^ Wait, what?

1. 9700Pro/9800Pro destroyed GeForce 5 series. GeForce 5 was the worst series ever made by NV in its history. It had non-existent DX9 performance (HL2 *cough*) and atrocious tri-linear filtering / anisotropic filtering optimizations. 9500Pro also unlocked into a 9700.

2. X800XT/X850XT once again beat 6800U in most GPU demanding titles. NV's only trump card that generation were OpenGL titles/flight sims and the sweet spot offered by 6800GT. However, X800XL offered awesome price/peformrance, while X800GTO2 unlocked into an X800XT!

3. X1800XT wasn't great but X1950XT series destroyed GeForce 7 in shader intensive games. One of the reasons 8800GTX looked so amazing is that by the time it launched, GeForce 7900GTX was completely failing in DX9 shader intensive games.

If you looked at overall raw performance in those generations:

9700Pro > FX5800U
9800XT > FX5950U
X850XT PE > 6800U/UE
X1950XTX > 7900GTX

NV wasn't even on the map back then. It's only after AMD bought ATI and NV made a big push into Tesla/Quadro markets with their "Big Die strategy" that they became the indisputable class leader in GPU performance. Until then ATI was beating them nearly every generation since R300. Oh, and in terms of 2D image quality, NV didn't get on the same level until Fermi generation. Everything before GeForce 8 had piss-poor 2D IQ on NV. Same story with anti-aliasing. NV's AA quality sucked so bad until GeForce 8 that you had to use 4xMSAA to match AMD's 2xMSAA.

Yeah those benchmarks are nuts. Im waiting for more official Crysis 3 benchamkrs as well as the Titan benchamrks emargo to be lifted. The more I think about it, a 7970 seems like the best investment at this point. They should hit 300 bucks in a few months as I already see them for 349. I also may decide to wait until later this year and ride out my GTX 670s...

Looking at CPU benchmakrs, it's encouraging for AMD to see game development move away from 2-3 CPU usage. By the looks of things, AMD will have another CPU in the AM3+ socket -  http://www.tomshardware.com/news/SABERTOOTH-990FX-GEN3-ASUS-Motherboard,21140.html

Why else would Asus be making PCIe 3.0 enabled board? 8350 doesn't support it.

Here is what's nuts: no matter how impressive the Titan is, NV's Maxwell is the greatest increase in computational performance on a per watt basis in their history and it's coming in 2014. If you thought Fermi -> Kepler was a big improvement with the Titan over GTX580, Maxwell should make the Titan look like a a mid-range card in late 2014. I am guessing a GM104 Maxwell will come very close to the Titan for $500 next year and Maxwell's flagship card, let's call it Zeus, should be out of this world on 20nm at 250W TDP. I wouldn't be surprised if it ends up being 50-70% faster than the Titan at $1K. Not sure if NV will delay it to 2015 though.

lol

Delay a year, BACKWARDS IN TIME, to make it look like they'd stuck to a two year cadence. First roadmap was 2010, yet the 2009 and 2007 products were moved to 2008 and 2010 by the second pic.

I just posted a benchmarks thread to keep things tidy.

Looking at early benchmakrs I'd say Titan is a bust at 1000 bucks. At 799, maybe but not worth a 1000.

Yup, it's an amazing card but an absolute joke for the price.

For multi-monitor gaming, it's just 36% faster than a 1050mhz 7970 and that's with the Titan overclocked to 1Ghz. Otherwise, it's only 25% faster!

Performance incresae is a fail for a 230% price increase (Newegg has 1100mhz 7970 for $430 by Gigabyte)

Here is a nice thread on triple monitor gaming of GTX600 vs. HD7000: http://forums.overclockers.co.uk/showthread.php?t=18455827

The Titan only makes sense if you get 2-3 of them. Otherwise, a $500 Asus Matrix Platinum @ 1300mhz would not be far behind honestly.

I think $500 20nm GPUs next year will match the Titan since going from HD6970 to 7970 and from 580 to 680 gave 35%-45% more performance with a node shrink. Titan sounds like an e-peen swinging card aimed at benchmarkers or people with very high incomes or if you need its double precision/compute performance for light workstation use. Would have been a lot more attractive at $699.

HD7970 OC vs. Titan OC.

HD7970@1265/1735:

Only 31% more performance from a $1000 551mm² chip overclocked. I am saving my money for 20nm for sure :)

Sod all that...

My Dell U3011 at 2560x1600 kinda demands a crossfire/sli setup, may well get this card, it's surprisingly powerful if overprice and will likely maintain most of it's value if sold a good couple of months before the successor.

Bloody hate SLI/crossfire, have 2 x 6950s with unlocked cores and the microstutter is just awful and got rid in the end, now have a 7970....as worked out as a very cheap upgrade with the free Bioshock/Crysis 3/Hitman/Sleeping Dogs/FarCry 3 offer after selling the codes...

Still...it's too slow for 2560x1600 with most recent new games on high

I paid $750 for each Radeon 7970 on launch and now they can be found for about $400 here, $1000 is probably fine as enthusiasts like myself would jump on it it like flies to poop and prices will drop after that initial sales surge.

Unfortunatly, reports are out that Titan isn't going to be an overclocking beast, so its the waiting game for me to see what AMD gives birth too and how well they clock or hoping someone like MSI implement a better power delivery system on Titan.
