Quad 7970s with 3 cards?

[kirbydude1234]

Every summer, I plan out how I'm going to upgrade my PC (I get more money in the summer due to more available hours) and this summer I want to upgrade my GPUs. I currently just have 1 reference visiontek 7970. Soon, I'm going to crossfire it with a sapphire 7970. However, I also plan on having about 6 monitors so I want another card and I was wondering if I could add either a 7990 or, when it comes out, the HIS X2 7970 (dual 7970) card onto those 2. It would be quad-GPU, but only using 3 slots. Would this work with all 3/4?
Thanks in advance

Specs:
i7-3770k @ 5GHz

I know I didn't have to include all this, but I love bragging.

Yes just like last gen 6990+6970=trifire! 7990+7970 would be a trifire configuration since there are 3 gpus. However I would highly recommend you pick another motherboard one with a PLX Chip and more PCIe spacing such as the Asus WS or the Asrock Extreme 9. This way you will not be bottleneck, also I would recommend buying 3 independent 7970's, and not the 7990!

Stay with your current 7970, there's a good possibility of new card being released this year from both sides.

What about the HIS 7970 X2? It's literally 2 7970s and completely blew away the 7990.

Another thing, I'm planning on having 2 7970s and a 7990/X2. Will THAT work?
