Re: Choosing between different brands of video card
reference cards are essentially the card that the manufacturer makes and slaps a fan on without any improvements to airflow design. It's hard to say if the reference coolers will be an issue, I would think in crossfire they might be, but the 6870 runs decently cool so I think with an intake fan on the side of the case you won't have any issues. If it is you can always slap on an aftermarket cooler.
A notice to EVERYONE who has posted here with a computer problem, I highly encourage you to keep current with the forums, even if it's browsing for 10-15 minutes during lunch, or before you go to bed at night. There are many things that you can learn and apply to future issues. My goal is to help people get to a point where they can use their own knowledge to help themselves, and others.
