My current graphics card could't take it, but I've watched probably a few hours worth of let's plays of it, so I get the gist. It looks great, and I'm sure I'd love it. I love what I've seen.
I played quite a bit of X3 on my last computer before it conked. I actually like the kind of inane depth it has because I have that kind of statistical meticulous personality. It's the reason I like the Paradox Grand Strategy games so much, Victoria 2 most of all. It'd be hard for me to pick between E: D and I guess X Rebirth is the latest one, since Elite also scatches my itch for really visceral sims better, but it doesn't scratch the managerial itch like the X series. (Edit. This is assuming the patches for XR made the game as good as X3. I saw the first release got abysmal ratings. If it still sucks, then I'll stick to X3 or wait for the rumored X4.)
Practically I imagine that'd mean I'd spend short bursts playing Elite for the sim parts, but I'd stick with X_ over a long game, but I'll need a new system to test that hypothesis. (Sort of a pipedream anyway since I don't have the time for massive time-sink games like I used to.)
