I dunno guys mine has been cherry, no inversion in any games, no weird power issues, no screen wake issues, acceptable BLB(for me and I like dark games) after setting it up. No problems with FS or 144hz also no issues running Skyrim, South Park and Hitman Abso at 60hz(preference).
I do use a very short 1m cable from Accel though. *Recommended by AMDMatt*
Good news is I might be selling the panel as my mobo is junk and I am probably going back to a cheap rig running 1080 @ 144hz.
My odyssey having my system built because I don't know how to do a custom loop has taught me to build yourself within your own means and don't trust anyone besides yourself to "test" hardware ...especially before plumbing it in to a hard tubed loop...
Wait, how do your MOBO being junk affects your decision of keeping the XL2730Z? The Universe is exploding inside me to know.
