If the es7000 is anything like the 8000 then 3d input lag is quite big, gaming will see a input lag in 3d of around 50/100ms,i had to return the 46 and 55 es8000 due to 2 major things ruining my gaming experience.
1) Way too much input lag in 3d , i hated gaming on it, move your stick and a few moments later the gun on screen will move, i sure as hell noticed this coming from a lower input lag 3dtv.
2) Massive amounts of motion blur at 60hz or any hz that did'nt use frame interpolation, looks like alot of modern 3dtv's, wether active or passive have put too much into frame interpolation to decrease motion blur instead of making there 60hz scanning backlight better to decrease motion blur/ghosting.
The lm7600 i have allso had and this set has very good input lag in 3d compared to the es8000 but it's still too much for me to race racing games.
It allso has terrible motion blur with any hz content that does'nt have frame interpolation enabled.
So 60hz 2d or 3d gaming has alot of motionblur and not by alittle either, both the samsung and lg was so bad for gaming my gaming went downhill for a few month !
I have included a picture of what the motion blur looks like, it's extremely bad imho and 2010/2011 lg passive 3dtv's had much less motion blur.
I'd suggest taking your pc to the shop and seeing what your 60hz gaming looks like with frame interpolation ect turned off if you can.http://www.displaymate.com/LCD_Response ... ootOut.htm
