Basically going from 4 core to 6 soon. I am going to sell this one but don't know how to clear the HD with everything already backed up. Any advice would be great! Thanks!

From 6,1 4-core to 6-core? does not (usually) require buying a whole new computer, the processor can be upgraded.

As for securely erasing an SSD, don't. You can format it as all free space.

I can just upgrade the cores on my own from the 4 core? Are you sure? Because me personally, i'd screw it up haha
 
Yes, the cpu in your 6,1 is in a socket. You can upgrade it to a 6, 8, 10, or 12 core. You do not need to buy another mac pro.
I had no clue, even though seeing a tutorial i'd probably screw this whole thing up costing me 3 grand

OS is connected to Apple ID
Recovery Mode is not going to wipe out the partitions like the Recovery partition you are using.

Your USB flash installer that you make and is bootable will though. No?

I can tell you I have three partitions. One tiny one, called EFI. A hidden one called 'Recovery HD'. And a big one called 'Macintosh HD'. That about all the information 'hidden' in your partition table. Unless you renamed your 'Macintosh HD' into your SSN or credit card number (including CVC) there's no need to delete any partitions.

If people are using the EFI or Recovery HD partitions to store data, that'd be mildly impressive. In this case, I think it's unlikely.
