I changed from a 226bw to a 2233RZ, definately nice for gaming, dunno how much i'd like going back though.

If your playing alot of QL (or other fast paced games) then go for it, else you could probably put the money towards the pc upgrade.

Another option, buy another 226bw and have dual monitors :)

just get and additional 120hz monitor, 2 monitors > 1 monitor

What 120hz LCD monitors are available besides the Samsung 2233rz?

acer and alienware has models as well.

acer, lg, alienware, viewsonic, asus... there are quite many already

if one was planning on attending competitive events, what monitor/refresh rate would be best to practice on?

Shitty 60hz ones probably.
