New Monitor

I'm getting closer and closer to making a final decision on a new monitor. I'm upgrading from a Dell e173FP and right now I think I've narrowed it down to these choices: Dell SP2008WFP, Samsung 2220WM or Samsung 942BW
I don't really want a big huge monitor thats why I'm kind of iffy on upgrading to a 22" plus no matter where I look it won't tell me the pixel pitch for this monitor. The height adjustment would be great on the 942BW but its not the end of the world if I don't have one and I don't want to sacrifice quality for it. I'm not that familiar with monitors so I'm not entirely sure if the 19" loses quality over the other 2 or not. The dell is probably around the perfect size for me but it is a good amount more money than the other 2. I'm not sure I really care for the silver color, I would prefer black but again quality is a lot more important to me. I'm a gamer and a web/graphic designer so I need a good monitor. Which would you guys go with if you were in my shoes? Another thing I was wondering is if a resolution that much bigger from 1280 x 1024 would take a toll on my PC's performance.
