16GB DDR4 2400 DIMMs run about $67 retail. So about 1/10 of the total cost of that board. It's a little apples and oranges, but since it seems like they just plucked down the same 8 chips you'd find on a DIMM right to the board maybe not that much.

I note that it has a PCIe x8 slot, but they don't have drivers for a video card (or any card) yet so it's kinda useless.

People have been running Radeon graphics cards with Linux desktop and the open source driver on the predecessor HiFive Unleashed board for literally three years already.

You can complain that you don't want to spend that much on a graphics card [1] but you can't complain that it's not supported.

[1] cheaper ones will work too

Then they should probably mention that on their page, which only says that graphics cards are being planned for but not currently supported.
