Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
From what I've seen, Broadwell-E "will be compatible with current generation X99 motherboards that feature the LGA 2011-v3 socket." (Citing reference)
I've been tossing around the idea too, but might wait for more data. Those prices on the 5820K and 5930K at Microcenter are pretty tempting...
Thought this was a pretty good deal: Corsair Carbide Series Air 540 High Airflow ATX Cube Case CC-9011030-WW - Black for $100.99

Not sure it's enough to justify upgrading from my i7-2600K either. I think I'll spend the money on new pipes for one of the bikes instead. Will see what things look like next year with DX12 and such.
