no im just looking at getting new specs, so is that the cheapest way? Would it be possible to use the R9 270x with my computer? If so what type of power supply would be good with that?
In your original post you ask what was needed to play at ultra settings. That is the answer you received.
Adding a R9 270 will get you medium to high settings on the single player.
And lower on the multiplayer.
BF4 needs a fast (true) quad core for good multiplayer gameplay. And an high end video card for ultra settings.
