Had the same mod on my 7950, and it was brilliant, what makes it even better with the 290x series is you no longer need the copper shim.
Furthermore I have close friend has just ordered two 290 to replace his existing crossfire 7950's that were also running via dwood brackets and antec 620 solution.
Hopefully get him to post some images of how they run in crossfire with temps + vrm temps
