do correct me. Benq XL2411Z (rm1199) doesnt support G-sync while Acer XB240H (RM999) support g-sync

The cheapest 144Hz monitor in Malaysia is Acer XB240H (without GSync), less than 1k now.

And there is only 1 1080p 144Hz GSync monitor in Malaysia, that's Acer Predator XB241H, AOC one doesn't exist in local market.

The next cheapest GSync monitor after XB241H is Acer Predator XB280HK, 4K UHD 60Hz, around 2.5k

You DONT NEED to have 100+ fps when you have G-Sync running. That's the beauty of G-Sync, it's  synchronizes low frames and sequence it so that each slow frame-timed frames are kept in the G-Sync module buffer and pushed out in correct sequence/interval so that the end result looks smooth on the display. If you strive for 100+ on 4K or even max settings at 2K, no single graphics card in existence is able to produce that on modern games.

My personal settings, in 2K I enable SMAA at most, and still be able to get above 60fps, doom regularly stays above 80fps, and drops to lower 70s when the action gets intense. Now, 70-80fps isnt shitty or out of sync when you have 100hz or 144Hz displays with G-Sync, because G-Sync sequence them into the G-Sync module buffer and display them as smooth frames with indistinguishable frame-times. The reason why most of folks are TARGETING close to 100hz or 144hz is because they want the game to perform as close at the display panel is natively meant to. The problem in this is that you either have to drop quality settings or drop resolution. Which is why most folks use this reason as not to invest in high end graphics cards until <insert whatever year>, but as modern game engine progresses, more complexities like geometric detail, textures, etc are added, and you've back to square one: your most powerful card now back to the point where it cannot get back to your precious 100-144Hz framerate. G-Sync eliminates that need to be close to those 100-144hz target, you can be at 40fps at one point and 110fps, G-Sync eliminates that and sync it back to the display panel refresh rate.

So, even back on my previous 4K60 G-Sync panel, I can be gaming at 35fps on the most punishing settings on GTAV on a single card (980Ti before I sold this), and it still looks as smooth as if it is running on 60fps the display panel is rated to. I have since moved this rig to be running on a 4KTV with 60hz refresh rate, I'll strive to get 60fps when I could but I will be able to see it if it drops to 35fps, the stutter and jerkyness.

In short,
You WANT to game at low frame rate (to a certain point) so that G-Sync covers your stutters at those framerates. You DO NOT wanna framerates HIGHER than your G-Sync panel refreshes because V-Sync will automatically kick in and introduce input lag.

My own preference : at 3440x1440 I can live with SMAA. At 4K, I don't even need any AA, the pixels are so fine and small, at such high pixel density, it gives you free AA. Purposely killing your system with TSSAA, or maximum AA with no appreciable gain at higher pixel density displays, is just you making excuse that current crop of graphics cards isn't capable enough at these resolutions.

Since ur looking or 144Hz monitor, can consider Dell S2716DG with NVIDIA®  G-Sync.
It also has DP 1.2 port. More info below...

PM me for best price!

I'm using Gsync 144hz IPS, I will recommend priorities as:

1. IPS
2. Gsync
3. 144hz
4. 1ms

That's just me, I'm okay with IPS glow, and I can't stand screen tearing.
