That might depend on what you value in gaming. If you like the deep rumble of explosions and gunshots, maybe. If you feel that that low end rumble gets in the way of the finer details, particularly positional cues, it might be problematic.
It's strange that everybody mentions the low end on these because I don't find the bass to be over blown at all. The highs are crisp and can get a little edgy but I have no issues with directional cues when playing Arma 3. Then again I'm using Scout Mode through my Sound Blaster ZxR. I mean these are after all studio monitors that the public got hold of and started buying in mass quantities hence the hype. Obviously open cans are better suited to some games.
I also use them through my trusty old iBasso D6 with MusicBee and the asio4all driver for music and they sound pretty bloody good. I like them.
Sorry for going off topic - again.
