Where did you buy your monitors from? ....
Well I'm in Australia and I do a lot of shopping around, I got the best deal from: http://www.scorptech.com.au/
But for future hardware purchases (not monitors) I'm thinking of going with Amazon, because of the strong Aussie dollar and they ship hardware to Australia. I will be taking a risk in terms of warranty though.
I'm looking for a good 120hertz monitor, or a 2560x1440not sure what will give me more gaming eye candy
That's really a personal preference, you need to visit a few stores and ask them to demo a screen for you.
I personally like 1080 HD as this is pretty much the standard for gaming for now as many games are now cross-platformed (PC, PS3, XBoX 360) etc and you can actually use HD TV's for gaming now at a cheaper price than what a dedicated PC display costs. My son recently got a 32" Full 1080p HD TV at 100Hz for his PC for $500. The games look great, they're silky smooth as the graphics card isn't locked at 60Hz and he gets to watch TV as well.
