Always ran XP Pro on all my systems, bought a broken Dell Inspiron n411z, fixed it and have had it running windows 7 ultimate. Since downgrading to XP is out the window I have dual booted mac osx (biggest hassle ever), and windows 8, neither of which I liked very much and am now considering trying Linux. I wouldn't say I am a pro with computers but I know enough to navigate around. Just need help determining with my computer specifications the best version to run. Just want something smooth running, good performance. All I really do with the pc is browse the web, burn dvds, use it to root and install custom roms on phones, videos, java based gaming. I appreciate all info, all computer specifics are located in the attached photos. Thanks!
