I am about to buy a new gaming rig, but I still currently have a 15 inch viewsonic LCD. Obviously, I need to upgrade the monitor. I suppose I can stretch my budget up to 500 dollars for the monitor. Problem is, my dorm desk space is extremely limited, so I don't think a CRT will be the best option. What LCDs are out there in the 19-21" range within my budget that are decent for gaming? Is there even anything within my budget? Am I just going to have to get a CRT?
