Looking to upgrade from older Plasma to LCD

Hello everyone!

I currently have a Panasonic TH50pz80u that is getting on in age. I was thinking about upgrading to an LCD type television. I mainly use my TV hooked up to my PC gaming rig to play games and as an extra desktop. Especially now with steam big picture mode its pretty great! I am interested in the quality of 3D. Mostly 3D from gaming since I would run it from my PC through my nvidia card.
My second biggest usage for it is Movies. I don't watch television at all.

My biggest problems with my current TV are the dithering and annoying buzzing noise it makes. Oh and its a furnace in the summer time!

I was looking to upgrade to a Samsung UN55ES7500. I could possibly swing the ES8000 if it is really worth the extra money but would rather not shell it out. From what it looks like the TV supports chroma 4:4:4 which is great.

Would the picture quality upgrade on the Samsung be worth ditching my current Panasonic plasma for?
Any input would be much appreciated!

Sorry to bump my own thread! Doing a bit more reading and the Sony HX850 looks like a contender too. It's the same price as the ES7500. Which TV would be the better option?

Anyone have any recommendations? I have been out of the game for a while.

Will there be an appreciable difference in picture quality from what I have now to a current generation TV?

My friend has a Sony tv, the picture is pretty good without him dialing it in buy the crosstalk on the 3d is really bad.
