well three posibles hear, while mrmacca takes a look.. 1) the texture file is blured its self. (fix in photoshop). 2) you have filters on.. like right above whare you load the file there is a filter setting. Tern it off, and try that. I don't remember but you never said if it was blury in renders also.. there is a difrence between what you see on screen (limited buy your v-card, and the render, not so limeted) and 3). I would try using a difrent work flow for getting the texture on there.. becouse your screen of the UV map looks way wired.. like there is a problem with it getting the UV map 1 to 1 with the texture.. I would right click on the object its self. assine a new matireal right there.. with that new matireal I would load the texture file in the color channel of that.. insted of makeing a seprat shader and draging it on to the ship.

let me know whats going on.. latter.
