LCD Newbie Questions

[SHRED]

I am looking into buying an LCD monitor.
I will run it with a 256mb eVGA GeForce 6800gs AGP.

My question is about the "wide screen" choices.
Are they compatible or are they "specialized"?
Will my card run them?
Is there any advantage or disadvantage?
What are some good buys right now on wide and regular screen?
Brands?
Models?
Is DVI capability important?
I also game, so no ghosting please.

Thanks for any suggestions.
