GeForce GTX Titan 3-way SLI and Multi monitor review

During the multi-display benchmarks, it's been stated that the cards seemed to be bottlenecked by the i7 @ 4.6ghz. Isn't this rather bandwidth limitations? Seeing the titan had the bandwidth upped from 256bit (compared to the 690, i know it says 512bit, but it's 2x256 effectivly) to 384bit. And thus having only a few more frames at these extreme settings. It displays itself on MSI afterburner als CPU bottleneck because the GPU load drops, but i dont think the CPU is the cause for this.

Just a theory ofc.

Titan is the best

I hope you guys start digging into frame latencies as that has been a hot topic lately.
Here's another article where Crossfire and the 7970 are shown to be almost 4x slower in frame delivery, resulting in stuttering. http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/60166-nvidia-gtx-titan-vs-sli-crossfire-15.html

There is also an article that shows the fps number of Crossfire may be inflated by so called runt frames, slivers of pixels not viewable but counted as fully rendered. http://www.pcper.com/reviews/Graphics-Cards/NVIDIA-GeForce-GTX-TITAN-Performance-Review-and-Frame-Rating-Update/Frame-Rat
Thus the Titan may actually be the best solution available , period.

I want to be this rich. GTX Titan 3-way SLI kind of rich. It´s amazing but the thing is, few years into the future we´re going to see this and laugh and mock it. And...that is a little sad for our wallets. Still impressive stuff!

I believe the issue of runt frames can be verified by overclocking or reducing settings (if need be) until your framerate is 60FPS or above (recommended to hover a bit higher than 60). Then, apply VSync, and check output. If there are no dropped frames and all frames are being displayed (can be checked by eye, since any frame(s) out of the ordinary can be noticed mostly), then the cards are able to render those frames since the beginning, and the FPS inflation would be untrue, or at least, an exception rather than the rule.

I say this because I get microstutter with VSync off on Heaven 3.0, along with maybe some / all of the problems mentioned, and my FPS hovers slightly above 60FPS. Enable VSync, and the output is buttery-smooth. The 60FPS are all being fully rendered, and there are no anomalies apart from the slight dip in FPS that happens as you pan around Heaven (happens with single card as well, probably on other cards and drivers as well, probably Unigine Heaven's fault).
