In case you do decide to try coming back, I would keep an eye out for the new upgrade campaign. It might help you save a bit of money in the event you decide to come back!

(Albeit I am unsure if you had to actually own a ps4 at the time of the upgrade in the last campaign... might still be worth looking into!)

Edit: or... well, I heard about dx11, Im not sure which is the case here :x
