System for Photo Editing

Hello.

I am looking for a system for photography (editing). I have been using my laptop for some time but it cant really handle what I am putting it through and the screen just isnt up to it.

So far my research tells me that I dont really need to be targeting a high end graphics card and the most important thing the moniter. Now I dont want to be hanging around waiting for my adobe programs to respond in fact I dont want to have any lagg.

to say I am confused is an understatment, there are so many systems out there and choices of moniter I just dont know where to go next?

can anyone recommend specs I should be looking for? and most importantly a moniter? so far I keep going back to the Dell 2208WFP???

Help!!!!

Appreciate your help, oh and my budget is £700 MAX!!!!
