Guys a simple question... I'm stuck with a Geforce 7900 GTX and a Core 2 6600 2.4 at the moment, and 2 gigs of ram. And I want to play Dayz... definitely. Can I just fix the problem changin the video board or it's better to change everything? Obviously I would like to play it like in the streams on twitch tv...pretty maximum detail... Can you give some general hint here? thanks!
