I've heard many mixed results when you triple stack.. Do you think they definitely justify themselves and have you ran into any issues with them?

Hi Mike,
hope your enjoying the planning mate, thats the part I like best actually.
In days gone by, scaling for SLI and Crossfire could be anywhere from good to terrible, but nowadays its pretty damn good, with the latest generation cards like these often achieving 100% scaling upgrade per card.
If your interested in what yours can do, try popping "6990 Crossfire scaling" into Google and your bound to come up with some comprehensive reviews as its a great card that has sold well.
