I can't decide. Even with a $1K budget, whether to get a high-end 24" (NEC) or mid-grade 27" (U2711) or 30" (E3011). I really don't know what I want.
I still have my trusty DELL FP2001. I don't want anything smaller in terms of screen height, but I do want something larger in terms of diagonal size (wide screen).
I primarily want it for digital photo and general office work. Gaming would be third on my list of priorities. If 3D gaming is where it's all going, and I intend to keep my next monitor for another 5-10 years, then sure, 3D capability might be a plus.
