I have an Asus Rampage Xtreme III with an i7 920 CPU on at the moment. I am looking to upgrade such CPU to something like a 980X - 990x or even one from the server line of CPUs. Can this MB support an Intel Xeon X5690 CPU with non-ECC memory ? or should I stick with 980X. I should also mention that I plan on having 6x8GB DDR3 Hyper X Fury installed on all DIMMs and what to know if the Xeon can support these in case I should head down the Xeon path. Thank you.
