If you're looking for 50 euro graphics card that can run DayZ, probably not your most ideal. But, you could get the Radeon HD 5450 that can play it at 19 fps. Or the R7 240, you can get 33 fps avg.
lol OP if you are going to save up for a 260x, you mind as well save up for a GTX 970. No point in stopping at 260x. Plus your CPU is fine at handling it without issue.
