I posted an ad on kijiji, (canadian craigslist), saying I was looking for new or used gtx 960/970s or 280xs or 280. I am looking to build a new pc and so I figure I could save a little on a graphics card. This guy comes outta nowhere and tells me I could buy his unovercloked gtx 780 lightning for 300$ (cad so like 250 usd). I know it is a crazy deal but I am only looking to spend 250.... Should I do it. However I am also worried it is a little out dated. Or will this card last me a little while (like 3 years) .
