You can do 7970 and 7950 cf. Because the 7950 its a bit slower you increase the latency a bit. But not a big deal a lot of people here run 7970 +7950

they will run at their speeds but probly will be best to run them the same clock will be much smoother and that shouldnt be a problem unless your trying to run them at 1200mhz or somthing.

I bought a second sapphire 7970 dual-x to xfire with my current sapphire 7970.Now the problem is that these cards are 2.5 slot cards and there isn't space on the second pci-e slot to put my second 7970 on.My case is a corsair 500r and motherboard is asus maximus v gene.How can I crossfire my 7970's without changing my motherboard?

Being that there really isn't any space in between the PCI-e slots on your board, I would say that you have 3 options.

Option A: Buy a different motherboard.

Option B: Return the 2nd 7970 and enjoy playing games at still great FPS with only one until AMD releases the next series of cards.

Option C: Replace the fans with waterblocks (along with a whole water cooling system of course)

I would personally go with Option A. Then you're future proofed for a bit. Unfortunately, either A or C are going to cost your more money, C costing the most money.

Thanks for the reply.I was considering option A myself, but the gene being an rog and such a fantastic motherboard, I don't want to let go off it.Also the resale value of hardware in my country is kinda poor, so even if I sell it and go for something like a z77 v pro, it is going to cost me additional $100 which imo is not worth it.

How about using a pci-e slot raiser cable or card and connecting my second 7970 to it? I don't have any idea about how this works,how to configure it and where will my second 7970 be seated in the case.

So, if anyone knows about configuring a pcie slot riser cable, please help me out.

A lot of risers allow you to put the card in at a right angle. It would essentially be laying face down on your motherboard; in the way of your lower slot and not allowing for proper air flow. That's also not to mention that it would probably and up hitting your PSU as your rocking a mid tower. AND, how are you going to connect the xfire bridge that way?
