I'm selling my r7 260 1gb model from sapphire to my friend, but I noticed that his card is a very good performing card, which is the 550 ti from nvidia. He only plays games at 900p, which is 1600x900, so is it worth it if he buys my 260x? BTW, my 260x is the oc version from sapphire. I mean I had a very good experience playing with the 260x on a 1080p resolution, it crushed games at 1080p ultra settings. So in simpler words, is it worth it to upgrade his card to the 260x which is the card I used.
