There shouldn't be a huge issue with scalpers for the RX 480 as the supply will be fairly large.

The GTX 1070/80 underwent a prolonged paper launch due to very limited supply, which lead to the some ridiculous prices. AIBs are ramping up production so the price for Pascal should fall pretty soon.
4GB vs. 8GB? Good Question. If you are playing on a 1080p monitor and are not planning to upgrade your CPU any time soon, I would go for the cheaper 4GB version. I question whether a FX 4300 could drive graphics processing that uses up more than 4GB of VRAM. If you are considering doing a major overhaul of your PC (like a new CPU/Mobo) sometime during the lifetime of the RX 480, spending a little more for a 8GB non-reference card might be the better decision.
