@B6: How far down the road is official SLI support?

Just edit: Doesn't it sound strange, that your SLI is using 95% vram on both cards with 3gb each? You can simply see: With 2 lower cards with 1500 mb vram, you will be again bottlenecked, as u cannot use the other vram. Not very effective and that is, why sli isn't providing a way better performance on smaller sli rigs as desired.

And this is VERY often the case in games, that it do not take advantage of the vram. Normally the guys do not see it, as current games are not using a lot mor than 1 GB vram. But this is waste ...

I try not too risk a disagreement on the 1c forums but; The memory is not wasted if both GPUs are using it. Half of it would be wasted if you are not using SLI (and have two GPUs) as each GPU only accesses its own Vram.

I do of course know this to be true because I read it on the internet

What i wanted to say: Smaller cards are sufficiently using their vram.

A correction from my side concerning this: As cards are getting larger vram, multi gpu can be used without any limits, because every card has enough. Smaller cards in current sli state are less efficient, because they get bottlenecks and up to now and with current techniques, it will not change very soon.

That is why I always suggest not to upgrade with sli. Perhaps this changes, but i bet, that it will take several more years to take it into consideration without these doubts. I was not referring to your system, because you have too much reserves. U just can see, that it is not efficiently scaled and this is often the case.

Concerning sorround: New nvidias also have them ready for surround gaming, but sorry: I am also an nvidia guy normally, but when you talk about sorround gaming, eyefinity is the betterbsolution and ati cards are performing way better in high resolutions by nature. So, we have to wait for the real kepler to evaluate their behaviour.

Up to now, the 680 dies against 7970 in high res or better say ultra hgj res with triple monitor setup.
