Hi, After 6.66 years and ending on a red and black screen I think my Radeon 7870 has died this evening; therefore I'm after a replacement. I'm not a massive PC gamer and the 7870 was just about capable when I chucked something at it on 1080p resolution (even if it wasn't on high etc). I realise the market is very different compared to my last purchase, however I probably don't need the latest tech and I figured £200 was enough for me. I'm after bang for buck and longevity (that matches medium specs). Had a quick look and I see RX580 at ~£160. Not sure if it is worth stretching to the 1660 and RX590 just above the 200 mark. Is there much of a gain?
