"I need 16GBs of RAM to run virtual machines, video rendering etc., "
I have a 2014 11" MBA 4 gig/256 and it runs Win 8.1 in a VM Ware Fusion virtual machine without any issue. I also run FCPX and iMovie without any issues.
Are your rendering on the virtual machine? That would be a more difficult task with any of the machines.
I excpect the 8 gig rMP will do just fine.
Personally I have used OSX with 4, 8 and 16 GB and found unles one is running a multiple of programs which require lots of ram anything above 8 is almost pointless. But if I always recommend one buy the most ram they can afford just for peace of mind.
