Re: 1680x1050 Or 1900x1200?
if you are worried about dead pixels, you can do what i did.
I waited for a discount at Office Max (i think) and i got an 20.1 inch for $180 last year, and they have a great return policy, which was if i was unsatisfied with it, i can return it or exchange it for any reason at all. The one i bought had a dead pixel, returned it and got another one the next day, took only about 5 min for the swap.
Nice choice on the 4870 X2, i wish i could afford a GPU like that... but the 8800GT is working fine for me now, I'll get a new one when i cant max out games anymore.
