I've heard that 2 of this 6870 in crossfire can cause one of them to heat up because they exhaust into the case and outside the case. I'd like to know which 6870 you guys would recommend I crossfire with my current one or if just getting a 2nd one of the one I have would be a good idea. Also, if I get a different 6870 from the oen I have, which card should be on the bottom/top?
It's always the top card because it is so close to the 2nd card that gets hotter.I would reccomend just crossfiring with the same card.The gigabyte Windforce is a very cool running card to begin with so it should handle the extra heat from the 2nd card very well.
What are your full system specs?
Also I should let you know that if you get a different card you either have to O.C. it to meet your gigabyte card or O.C. your current card to meet the 2nd.Both cards have to run at the same speed if the don't the faster card is downclocked it meet the lower card.
