Which is best for Games

I know I know. Your all tired of hearing the same questions asked over and over LOL, once more won't hurt.

I am stuck. I currently have a Hitachi SuperScan Elite 630 17inch monitor. I have the Hercules geforce 2 64MB video card. I play alot of Unreal tournament, and other then that use the computer for mainly selling on Ebay, and websurfing. I want to upgrade to a new monitor but have no clue what I should get. Is a 19 big enough or would I be better off with a 21 inch. I sit pretty close to the computer so if that helps any.

Also what brands. I hear that viewsonic has not been as good as it used to be, but I would not rule it out. Any help would really be appricated. I have been banging my head trying to figure out what to buy.

If I did go with the 19inch sony I was looking at one of these two models.

CPD-G400 and the CPD-E400. Can anyone tell me the difference in them? What is a good refresh rate? <P ID="edit"><FONT SIZE=-1><EM>Edited by nydennis1 on 01/17/01 08:55 PM.</EM></FONT></P>
