I bought the card about a year ago (I think) for £190. It's served me very well, but I just yearned for GTA V on max settings with a decent FPS, which is something the 270X has finally met it's maker on. It can handle around high/medium settings with around 60fps.
You can find the specs here.
I'm looking for around £80
Thanks! I'll be posting this on eBay this Sunday if there's no takers on RD.
