I got the Syncmaster 920n from Samsung, and I am very happy about it ;-).
The dell screen is a widescreen, so it seems on what you like best, a 'normal' one, or a widescreen. (Tough i never seem to get the advantage of widescreens)

Also ram is on one of it's highpoints of price, so maybe better to wait till it's cheaper again, like a few months ago, or buy enough to come satisfy yourself, and then add some more later, when it's cheaper ;-).
