Standard resolution for a 19" wide screen is 1440x900.
Check things like the cooler, the warranty, and value-adds like free games. I usually buy HIS, but have also bought Asus cards. I will not buy Diamond, ever again. Sapphire is supposed to be decent, but I haven't personally bought any of their cards.
I like HIS. Every one I've bought has run well. The IceQ cooler is near-silent, and works. My father still has a 2+ year old HIS 2600 PRO. I'm still running a 1+ yr. old HD4850 and a HD4670.
Newegg reviews are of limited value. Reading between the lines will occasionally reveal an idiot, and they're the ones most likely to post bad reviews.
