You are the one trolling pal.
I had GTX 690 4-Way SLI in my ASUS P8P67 WS build with a 2700k at 5.1ghz. I have GTX 680 3-Way SLI in my ASUS X79 Sabertooth with a 3930k at 5ghz and have one of the GTX 690s from that previous build in another identical X79 Sabertooth build.
4-Way SLI does not scale as well as 3-Way SLI. It is faster though but isn't perfect or worth the price you pay for it. 3-Way is the sweet spot and in previous generations actually smoothed out and helped micro stutter in SLI and Crossfire systems. It did in my HD 6990 + HD 6970 system for sure. There were some reviews on it which actually confirmed it too.
Don't agree with the X79 micro stutter statement at all. That's a bunch of rubbish. Maybe in cheaper board designs but not in quality ASUS boards. I've had up to 4-Way SLI and crossfire in my current build and never experienced any microstutter with my final set-ups. I have experienced it with radeonpro pro and trying different settings with my Lightning set-up, but they were merely tests and radeonpro pro in the end actually reduces and eliminates microstutter with the right settings. So thats rubbish. Maybe people are getting confused with hitting VRAM limits, maybe something else is causing it but most probably they don't know what they are doing.
Microstutter was rampant last generation in the AMD line-up and in the GTX 590. AMD had some with the HD 7970 when it first are out but since has been fixed and radeonpro pro had it fixed for some time also. AMD cards are now smooth and the performance is shockingly good as we all know. They really turned stuff around since last generation which were a mess.
So no. Everyone screaming microstutter as a way to justify a Titan is misinformed. GTX 690s of all cards have built in preventative measures for this and the cards do not Exhibit from any noticeable microstutter. I've had two, have only one now and had since launch and it's an amazing card in that regard. The powercolor HD 7990 doesn't have any microstutter either. Had a Devil for a short while and it was a premium piece of equipment.
As for the rest of what he said Titan SLI overclocked will beat 3-Way GTX 680 and 3-Way Titan SLI reference will beat 4-Way GTX 680 at 1600P and above (as for 1080P, Lol, who cares). Even if it's only 30% faster. SLI doesn't always scale 100% when getting over two cards so it doesn't have a huge task ahead of it and with everything we've seen so far the Titan despite our worst fears seems like it will be a very fast card. Not faster than a GTX 690 at reference speeds but that was far too optimistic an assumption anyways. Maybe in some cases it could but overall I would doubt it and it definatly will not be worth the $1200-1600 price tag they put on them over here.
