I am being forced into buying a new monitor because my old one is going towards a different family members PC. I am looking at the Dell 2005. I had a 17 inch MAG LCD and it was pretty good despite the name on it. Am I gonna se a big differnce between the 17 and the Dell 2005 when talking about size and performance ? Or I should I just get a 2405 and spend the extra, I just want to be apaled really....
