Seems SLI is not scaling that well in all games with Keplars....strange
Makes sense. Much of Kepler's strength comes from GPU boost. In multi-card configurations, load needs to be balanced correctly or you get stuttering waiting for one card to catch up. Odds are GPU boost doesn't work quite the same in SLI since no two cards will clock the same with power usage.

Another problem with this is that on air, the inside card will be hotter than the outside card, lowering its ability to benefit from GPU boost. So essentially what we are seeing is the "no GPU boost" cards in SLI, compared to the single card.

Looks like good SLI setups will require cards that are water cooled and have comparable OC headroom.

I think a lot of people are missing the fact that at stock speeds, odds are the 680 is equal to or slower than the 7970. The GPU boost is what gives it the single card performance crown.

HEHEHEH!

I'm sure nVidia wont allow this to hamper SLi performance. It'll be resolved soon enough.

Yup- this is the end for AMD. This time next year there will only be Intel and nVidia.

*high fives everybody*

There is one thing I will say about these cards is they are quiet, way more than the 580's were benching.

Hmm hybrid water and air cooling solution from Inno3D?

Great in banchmarks so far. I have been watching the Rugby League, so haven't tried games, but it's on my list.

At what cost ? Most of the 3GB GTX 580's are still upto 150 more than a GTX680 and for how much performance gain ?

The more i look at it the more i want to wait for the other keplers. Nvidia have a more powerful single GPU solution to be out around fall...maybe it could be a refresh card GTX685 ? either way the rumoured 384 bit memory bus and 4GB GDDR5 memory sound more appealing for a next gen card and no doubt it would scale better in SLI and in multi monitor setups.

Well just finished some Battlefield 3 and it's so smooth. I can't explain it any other way. Compared to the 580's it like silky smooth.

Was hoping someone can help out..was thinking of getting GTX 680, but reading elsewhere there is a 4 GB version coming out.

If I only have one single monitor @ 1920x1080 do I need that 4 GB or 2 GB will be fine to say play BF3 in ultra?

I was not planning on doing SLI. I just want to know if I spend $500 will I be able to play everything max right now
