few incorrect statements.. but yes it will work.

*Xfire does not care if GPU's are run at different speeds...and WILL NOT 'retard' a faster GPU to match the slower
*..6970 -> 6870 are Xfire capable...

Umm, you are incorrect. 68xx will only CF with 68xx and 6790. CF will also bump down the speeds :/

nice troll.. but I dont think so.

I already stated - "so long as they have xfire connections" ... 6790 is the lowest model GPU that has them.. so how could you expect to xfire anything below it?

*Also, Xfire doesn't give a crap about different GPU speeds at all.. this is a well known fact 'Google' can help you with wink.gif

ie- a 6870+6850 in xfire = both cards at their respective speeds.. the 6870 is not downclocked at ALL!

speeds dont matter but you cant crossfire any 6xxx series with another. IE you cant crossfire a 6970 with a 6870

Correct, the 69xx cant crossfire with 68xx. But, we've been talking about the 6870 and 6850 crossfiring. The 6870 and 6850 will crossfire with no problems and the 6870 will not be slowed to match the 6850. The resulting performance would be somewhere between 6870 xfire and 6850 xfire.

Also, that 650 PSU may not have enough PCIe connectors. You will need 4x 6pin connectors.
