So my understanding is that with the new crossfire X, you can have two totally different ATI cards (as long as they support crossfire X), and have them running in crossfire, but at their respective clocks? I have a 4850 512mb. Let's just say for the sake of the argument that its clock is 300, and i bought a 4950 with a clock of 400 with 2 gigs of memory, etc. So, in crossfireX, they would run each at their own clock, instead of both running at the performance of the lesser card, correct?
 
When you say "New" CrossFire X are you saying that ATI has developed new technology to allow mixing of processor famlies, because as far as I know you need to stay within a family when linking cards. But yes according to the chart you can link a 4850 and a 4950, but it's also my understanding that the faster clock and the larger memory will be slowed or size reduced to match the lesser card.

Hmm, I think I misread the wiki article
http://en.wikipedia.org/wiki/ATI_CrossFire

Thanks for the chart, though, it helps :good:
 
Wikipedia isn't always your friend. 4950? Is this a new GPU i don't know about? I thought we were just up to the 4890's
