Best £150 AMD GPU

[3key]

I have a budget of £150 to upgrade from a heavily oced R9 270. Can be new or used. Currently have a FX 8320 @4ghz which shoulden't bottleneck anything in this price range, unless someone can find a Titan X-P for this price! Going AMD as I'm a bit of a fanboy and have a red build with a nice freesync monitor (Sadly, my R9 270 dosen't support Freesync). My budget may increase to around £210 as selling another 270x for £75, but as it's not selling and someone made an offer of £50 I may take that. Replies are appreciated.

Rx 470 or 480 if you can find one.
