Benching? No, unless you have some type of Vsync enabled. I am not sure if Vsync is 120Hz capable in any games though, might be worth looking at

)
The 120Hz feature for HDTV is largely a marketing one, and really only refers to BluRay playback, in which the 120Hz feature benefits from an even source:display ratio (24 goes into 120 evenly). Generally speaking 120Hz is a new processor that handles some image blurring and judder fixing issues from what I understand. Not TRUE 120Hz like a LCD monitor.
Still for 120Hz TVs look up "soap opera effect" sure you have no motion lag, but films look like TV movies...
As far as 120Hz
Monitors. Information is a bit more skeptical. Opinions are only valuable from blind reviews. (lol not joking) As once you know XXX monitor is better than YYY opinions just naturally get skewed towards XXX.
Unfortunately windows shopping will not help much unless the store knows how to properly calibrate each separate screen per the media source.
Considering the large price difference, I think you would be better off with a higher quality 60HZ monitor (Like an IPS). This improves picture quality and has good response times.
I would do some research though. I would go with one of those new 24" LCDs from Korea solely due to the 2400 something resolution, and the low cost which higher res will push your max FPS down to 60 or so anyway, and you would not notice the difference between 60 and 120 hz.
Response time is more important than refresh anyway

Just watch out. Some monitors will advertise say 7ms response time, others will say 2ms. the 7ms may be better if they are talking about BWB not GTG. True response time is Black to white to black not Grey to whit to grey time which most LCDs use to get that 2ms advertising thang.
I have no personal recommendation for a monitor for you, I cant spend what I would want to on a monitor, they cost as much as my PC! lol. So therefore I try not to look. High res is most important to me, I joined the LCD game late (had 24" WS Crts

), so things like ghosting and such were never an issue for me.
Sorry for another long post
