I think you should go for 900NF, 955df (like mine) will probobly have distortion (curvature on the top or bottom line), or try PF790 from viewSonic, many gamers own it, love it!
Don't get anything from Samsung! I have looked at Samsungs, and they just don't have any contrast at all. Eveything looks greyish and blah. I have a viewsonic pf790, the colors are vivid, and it is great for games and anything else you may use on it. Also I got it refurbished for cheap.
