Aphasia wrote:Silent is a subjective opinion though. And these days, I want something with a much lower noise floor then I used earlier. I also never use headphones when gaming so that is also a factor for me.
I found the reference design of 6970 under load to have significantly noise when gaming with it. So bad as to drown out footsteps, etc, actually hindering my enjoyment when gaming. And yes, the annoying part is either you needed a steady and slightly to high fan rpm that was too noisy, or you needed to listen to the fan go up and down as the profile on the 6970 wasn't geared for a steady rpm but immediate temperature control. So what you actually got when under high load was this cyclic dustbuster that revved every 10 seconds or so. Or you could set it manually to a more steady, but slightly too noisy level.

Mutli-gpu solutions are the poor cousin, the kludge, the half-assed solution to not having a fast-enough GPU.
Sure, with enough smoke and mirrors, enough lipstick, you really can make a pig look pretty.
(pro tip; they're still pigs, even if you do have two of them)

There was no we. It was just me. A thousand apologies.
Would you prefer SLI Ready PSU?

Hang on. I have to find my pen.
This thread is highly suspecious due to such a naïve question. No more replies from the author. But there is a very large icon with a link to some website. How many people actually clicked on it?

Multi-GPU solutions are challenged on this front, but single-GPU graphics cards aren't entirely in the clear, either. New technologies and clever algorithms may be needed in order to conquer this next frontier. GPU makers have some work to do, especially if they wish to continue selling multi-GPU cards and configs as premium products.
The FCAT analysis has shown us that Nvidia's frame metering tech for SLI does seem to work as advertised. Frame metering isn't necessarily a perfect solution, because it does insert some tiny delays into the rendering-and-display pipeline. Those delays may create timing discontinuities between the game simulation time—and thus frame content—and the display time. They also add a minuscule bit to the lag between user input and visual response. But then there's apparently a fair amount of low-stakes timing slop in PC graphics, as the gap between our Fraps and FCAT results (in everything but the Unreal-engine-based Borderlands 2) has demonstrated. The best thing we can say for frame metering is that it makes the Fraps and FCAT times for SLI solutions appear to correlate about like they do for single-GPU solutions. That's a really high-concept way of saying that it appears to work pretty well.

Chrispy_ wrote:I have had both types of SLI (3DFx and Nvidia) as well as a couple of dual and quad Crossfire configs; My experience matches the articles around the web - concluding that even, lag-free frame delivery is far more complex than a FRAPS, DCAT or FPS average, and Mutli-GPU configs suck at it, even with frame-pacing driver wizardry.
