I've said that multiple times, VA is a solid compromise lol? The OP never said he was going to be watching movies on his PC, in fact he said FPS games are his "bread and butter". For FPS TN is king, and the 24" model that i own is rated higher than the 27":

Most important part of that review, its gaming prowess and responsiveness:
Responsiveness in games and movies
Where the frame rate kept pace with the 165Hz refresh rate (i.e. 165Hz) on BF1, the overall fluidity was excellent. The ‘connected feel’ as you interact with the game world was excellent, far superior to even the lowest latency 60Hz displays. The fact that the monitor was outputting 2.75 times as much visual information every second not only improved the ‘connected feeling’, but also greatly reduced perceived blur. This was obvious whether moving the mouse around and changing the character’s viewpoint, sprinting about or moving in a vehicle as the game world appeared more sharply focused. It was easier to track and engage ‘the bad guys’ as a result and for those sensitive to motion blur the experience was altogether less dizzying. With 165Hz/165fps, there was a slight advantage over even highly responsive 144Hz models (running at 144fps) such as the Dell S2716DG. This was true both in terms of the connected feel and level of perceived blur. The difference was only slight and much subtler than moving from 60Hz up to 100Hz or from 100Hz up to 144Hz. And indeed sensitivity to this varies, so not everybody will appreciate this quite as much as others anyway. One thing we feel may be more broadly appreciated is the complete lack of obvious overshoot, even during the transitions that troubled this model’s 27” counterpart. There was nothing more than the faintest hint during a small number of transitions, nothing eye-catching at all. Despite this, there was no noticeable conventional trailing either.
