I just got a very good deal from a friend for his two (slightly used) R9 290s, the problem is that one of them is Sapphire Tri-X and the other is Sapphire Vapor-X (links below respectively)

Now for obvious reasons I want to install the Vapor-X in the the slot that gets hotter, now here is my question; in a 2-way CrossFire, is there a primary card?, by that I mean a card that gets used the most and gets the hottest, or are graphical tasks divided equally that both cards heat at the same rate? and if one heats faster then which one?
I will be using this MB: http://www.asus.com/ae-en/Motherboards/SABERTOOTH_990FX_R20/overview/
Also I see that the cards have different memory and GPU core speeds, is that gonna be a problem?
And what about overclocking?, do I have to overclock each of them separately or what's the deal?
