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!

the bottleneck is the real point here... if it's sure it's going to happen I will go for a new machine. But it that's not gonna create big problems fixing with new components would allow me to save a lot of money...

Well...my benchmark is the streams I see on twitch tv (beand bandit and the like)... I can see they go for max details and still own other players... I also have the advantage of a super fast connection

thanks guys, I think I will try and do it with 2 more gigs of ram and a new video board...in order to spend maybe half of what would cost a new PC. I'm really not into high end games in PC (mostly strategy) but Dayz is something different I really want to play. So can you suggest a good video board? By good I mean enough to run full spec (or almost) and still not spending an awful lot of money...
