Just a quick update on getting 6.7 installed on a host using 'unsupported' processors.
I added a new host to my home lab recently. Once I had that up to the current 6.7 release (also updated vCenter before doing that) I was able to also update the old host to 6.7 (using the GA iso). This surprised me a bit since I wasn't able to do an install with the offline package previously. Either way, it did work in this instance. No way to know if this will work for everyone, or anyone else. But it's worth a try if you're looking to get onto 6.7 with older hardware. It also beats trying to do a clean install off of CD/ISO (if you have remote console access).
BTW, my new host is a small Supermicro box with IPMI (similar to iDRAC/iLO). I plan to get a second one within the next ~6 months so that I can use HA/DRS.
Also, I'm using licensing off of the VMUG Advantage membership. Well worth the $180-$200 a year IMO.
