I'm planning on going for the the ASUS Sabertooth Z77 with the i7 3770 (not the 'K' version).
I want to use 3 7970 Lightnings in crossfire with this setup. It is to my understanding that LGA 1155s do not provide more than 16 lanes of PCIE 3.0.
So basically my question is - can I use 3-way 7970 Lightning crossfire setup with the above mentioned components and ensure that the cards will be used to their full potential?
Correct me if I;m wrong, but tests suggest that the difference in performance between x8 and x16 slots is negligible. And I'm happy if I can run them at x8,x8,x4 setup.
If some other motherboard can fix this issue (please mention brand and model), I;m okay with getting that one instead of the Sabertooth. I just want to stick to this CPU is all.
Thanks a lot!
