[citation][nom]evga_fan[/nom]I think Chris summed it up pretty nicely. We now have a clear cut case at least until nvidias response, which frankly should suffer more or less from the same problems as the 6990.Go for 6970 CF or 570 SLi as opposed to 6990 that is louder, hotter, more expensive and last but not least, not as fast as its dual-card opposition. It never wins in any of these categories, EXCEPT the fact that you don't have to worry about CF motherboards and dual-card configs etc.It would also seem, from the numbers in the article, that a CF 6990 setup is a huge waste of cash seeing as it doesn't give that much performance boost over the single card setup.Finally I would just like to as Chris if he can put in the numbers for the 480 SLi (same tier as 6970 and 570) just to compare performance/noise/heat/price ratios.[/citation]
Hi evga_fan,
I didn't have time to run 480 SLI figures, but assume they'd be very close to the 570s. Noise would be another matter entirely. That configuration is notorious for howling in SLI mode.
As for CrossFire, I think it's pretty safe to say that really isn't a problem any more. NV is out of the chipset game, and every AMD/Intel-based board I've had through for years has been CrossFire-capable. SLI licensing has been more spotty, I'd say.
