Looking for a Good Monitor 30" (ish)

Hi there
Well im now looking to upgrade my monitor as i seem to lose track of people when im playing FAST paced games....
I currently have the Samsung 2232BW and it seems to flicker a bit....


So im looking for a Bigger and better Screen for around £300-400 but im not 100% sure what i should be looking for...

I believe:-
- Refresh rates are important (not sure about LED screens) but im not sure on Resolution.
- Dot Pitch (but this never seems to be displayed on the ones i look at  )
- Responce times (2ms or less i believe)


I been looking at this but i thinkn its only 50Hz which im not sure is good enough...
SAMSUNG UE32C4000 32" HD Ready LED Backlit TV

I can get this for about £300


Any better suggestions??

P.S Graphics card= Sapphire ATI 4870 1GB


Thanks for your help
