I'm posting this in the graphics card section because I'm not sure where else to start. I'm investigating new PC options (Dell XPS line, mainly) because my existing Alienware is dying and the warranty has long since expired. Anyway, my concern in configuring a new system, I am as always trying to future proof it as much as possible, without spending several thousand dollars. As such, I want it to be able to play back 4k video content and handle 4k gaming graphics (I'm not into MMOs at the moment, I'm mainly a Starcraft guy, so nothing too intense), when 4k arrives in earnest. I really don't know which parts of the computer, in addition to the graphics cards, I need to focus on for this, meaning would a mid-range XPS, hopefully within $1k, be enough? Also, I'm hoping that cloud gaming really comes into its own soon, including games like Starcraft, so that the demands on my desktop will be less and thus I don't need to spend nearly as much. Any guidance would be appreciated.
