Samsung and Viewsonic are both really good monitors. Just get something with a 8ms response time or lower and about 300 for brightness. A 17" will be sharper at lower resolutions like Beefcake said. My advice is to throw some game movies on a flash drive, go to an electronics store, and play them on various monitors to see if the difference in quality is a big deal to you. My 19" Samsung looks just fine to me, it might not for you.
