I have a BenQ RL2755 that I just picked up from Micro Center on sale last week. It's an older monitor, but works phenominal for gaming. I played a lot of Counter Strike and it worked perfect. I imagine that model you have works better.
The really cool thing about mine, and i'm sure the model you are looking at is much nicer, are plenty..
Pros:
1. Gaming looks great, and there are different pre-made setups for fighters, shooters, RPG's, movie mode, etc. The fighting mode looks top notch with my neo geo via XRGB, seriously 100 times better than the old LCD tv I was using before. In Counter Strike, which was shit on my old tv, everyone blended in the enviroment, and I couldn't see a damn thing, it is crisp, and easy to see everything.
2. There is a mode that is easy on the eyes, for regular web browsing. Since I spend a ton of time on my PC for school with programming projects, then gaming and movies, this is a god send. I seriously don't know how I lived without it. My headaches take much longer to set in, and my contacts dry out slower. That may not be relevant to you.
3. All the menu buttons are on the front, and is super easy to navigate, everything is labeled what every button does as you navigate the menu.
4. There's a decent headphone lever on the back for resting a headset.
5. The base of the monitor, fits xbox and PS3/4 controller perfect, it is made to do so, and has an anti-grip texture.
6. Also I havent tested yet, but I believe there is a headphone jack on the monitor, because it comes with a headphone cord. I believe you just plug that cord in the monitor, and the PC, then can hook a headset up to the monitor. Which if I read the manual right, and it works, would be nice. Effing around with PC sound setting can get frustrating.
Cons:
1. The sound is quiet, and no bass, you will want dedicated speakers, but if you are PC gaming, obviously a monitor is not ideal for sound.
I picked my RL2755 on sale at micro center for $200.00 even. Lower than amazon. They didn't have any vertical monitors for programming/taited games, under $600.00. So I just asked if they stocked BenQ stuff, and they said they actually had some in the back, just not on the floor. After they told me the price I bought it immediately.
I have heard that movies don't look good on these, because they are made for console gaming, but mine looks fine. I hear the newer models are taited, and I may pick up a second in the future, but I couldn't pass up $200.00 for a gaming monitor. I am very happy to say the least.
