I want to choose between 3options. 1: Pavilion HP desktop i58400 1tb HDD, 16 GIG Optane with 8 gig DRAM. 2: same computer with 16 GIG Optane with 16 GIG dram. 3: same computer with 16 gig DRAM. Using in small church to record and edit audio, to import and edit video and run a monitor and projector. And normal record keeping. Salesman told me Optane is ram. Found this isn't true.
