Just got my 55D8000. Amazon price matched a seller, so I got the TV, 4 pairs of glasses, 5 3d blurays, and a samsung 3d bluray player for $2475. Not bad! I plan on selling the player as I'm using my ps3 for everything. I've got the ps3 connected to a Denon AVR791 and a 5.1 M&K surround system.
Gaming performance - I'm a pretty hard core fps guy (used to be pc only), and I will complain about even the
slightest amount of input lag, ghosting, anything like that. I will tell you, this set with game mode on performs
perfectly well. I play black ops with the sensitivity at 10, and there is literally no noticeable lag.
3D - I am impressed. Calibration makes a HUGE difference in performance and visuals, and I've been messing around with settings for days and haven't quite found the perfect setup yet. I am blown away by the 3d pq and flawless performance the closer I get to perfect settings. In addition to watching 3d content on the ps3, I've also been checking out SBS 3d content I've downloaded on my quad i7 macbookpro and it looks great. Very positive experience there as well.
2d-3d conversion actually works amazingly well, despite many people claiming it to be worthless. I don't watch or play anything in less than 1080p, which may have something to do with other people not being as impressed. Low resolution content probably shouldn't be put into 3d anyway. Playing 2d ps3 games in 3d is actually incredibly entertaining and gorgeous (I especially love the effect with 3rd person shooters and the like), not to mention games like killzone 3 and crysis 2 which have stereo 3d and are incredible. Playing games in 3D is like crack. Once you start you just don't want to turn it off. The only time I do is when my eyes need a break after hours of playing, or if I'm serious about playing well in duty. Still haven't gotten used to there being depth in fast online matches
Issues? - I have not had any issues with the tv. The remote and glasses paired instantly. The closer I get to having correct calibration, the less and less I notice the small amount of corner clouding (which at this point is not noticeable at all during movies or playing games). I'm beginning to wonder if there's a large variance in the quality of each set, or if people having lots of issues with clouding and banding just haven't taken the time to turn it off dynamic mode and mess with some settings

If any one has any questions or would like me to test anything let me know!
Also, I use the TV in an apartment full of windows, and the thing is bright enough it works all day long. Pic related. (looks a bit washed - was pre-calibration, iphone photo in full daylight will do that)
