To those that have the money I say congrats!! I'd be on board to if it didn't cost more than my rent tongue.gif

Problem with the 2GB is at those settings on my 1200P surround set-up you're hitting around 55FPS which is good and using around 2100MB of VRAM but your cards become useless the day you want to add a third and turn the settings up because of your extra processing power.

Which is what I've always said. 2GB GTX 680 SLI and 2GB GTX 690 are fine for surround (as a budget set-up) if you turn your settings down but they are totally useless if you intend on adding another one because the extra performance you'll gain you'll never use, see or be able to take advantage of because games are so close to the VRAM limit.

Also because they are working so close to their limit, all cards suffer from microstutter in SLI when working at their limit and in Crysis 3 my 4GB GTX 680 SLI have much larger frametimes than a game like BF3 that can also max my cards. Which is another reason why GTX Titan is better because they won't be working as hard to produce such framerates in SLI and the frametimes will be lower. Much lower if run as a single card.

Would have loved to see GTX Titan SLI and VRAM usage in this review also.

I would't say the 2GB becomes useless with a third card. Sure you might see some issue crop up due to the 2GB vram but even so its worth remembering that currently there is no way of measuring actual used vram only reserved vram and thous two are not the same thing. Even when you truly run out of vram most engines will do texture swapping to keep things smooth. For example when running Crysis 1 @ 1080p it would run perfectly happily with my 1GB 4890's. With the same settings and a 2GB GTX 670 I would see 1.3GB reserved. The game didn't need the extra 300mb but as it was there it reserved it and perhaps cut down a bit on load times. I don't know they didn't seam to be shorter but perhaps they where.

I wouldn't run tri SLI either but not because of the vram but because 3-4 GPU setups have much more issues then dual GPU setups in general.

well the main thing here is that a single Titan will play smoother than 7970 crossfire, or any crossfire/sli setup. It's the dropped frames and small pauses that effects what you see most. They present the most jarring inconsistencies. That's where Titan has a very large advantage.

Well that's the main argument isn't it. You can look at numbers all day be it average FPS, min FPS, frame times and so on. None of them even combined tell the complete story. Even with a titan or any card you are always dropping frames. That's how it is when you don't run at a fixed frame rate. Numbers will never tell how noticeable the dropped frames and small pauses as that is effected as much by what is being displayed as how fast the displaying is being done.

I know a lot of Titan owners say that the Titan is much smoother then their SLI/crossfire setups but even though they are probably sincere it does not necessarily make what they say true. Placebo can be an powerful effect and so the titan might seam more smooth just because that's what the viewer wants/expects.

If you really wanted to answers the question what gives the best gaming experience you need to do a big blind test using a large as possible pool of gaming enthusiasts.

It is all theory.

I play BF3 everyday maxed at 1080p with no stutter. Or in other words no stutter I can see.

Far Cry 3 and Hitmain: Absolution are by far the worst offenders.

It isn't a theory. In those titles in particular, you can evidently see the stuttering.

I also want to mention that if your framerate is high enough (say around 70+) the stutters will be greatly minimized from a subjective perspective. This is because the deltas between average and max frame times may stay the same but they will be delivered so quickly, you won't notice the "peaks" so to speak.

FC3 is a nightmare to play in Crossfire. Nobody could possibly play that game with two AMD cards & say that frame lag isn't an issue.

And you're limited to adding in two more cards which can and will be beaten by three Titans by a significant margin, with room for a fourth Titan.

When Nvidia finally works out the SLI scaling on Titans...

I dont get all this "titan = bragging rights"

Show me a trend where users with Titans brag about the titan. They just wanted a single card solution which was a bit faster than any other single card solution. No ones bragging about it. Sure they look nice, but saying packaging of a video card/features it offers are nice is not bragging - its just liking the product.

A bunch of people saying "well if you want bragging rights get the titan" does not make titan owners braggarts.

Those people who said "bragging rights" are definitely wrong. I didn't see Titan users brag in this thread.
Just because some loser brag about his/ her Titans and his/ her income doesn't mean all the Titan users are all arrogant thumb.gif.
