Maybe a bit over the top for you but im using an 24" widescreen for several months now mainly play WoW on it but also some battlefield fps. I play games in its native res at 1920x1200 now.(intel core2duo at 3,2 ghz 2 gig ram 7950gx2 vidcard

Response time quoted on monitors is not entirely accurate too to measure this most manuafacters supply an best case scenario here aka in one situation it might be 4 ms response time but in a bad situation it might be 30 really best to just look up reviews on tthe net when you decided which one you want.

I use vsync usually to cap fps at 60 so it doesnt go over 60 fps and gets tearing. I dont notice any lag with this thing there supposed to be some small delay though some old tft monitors also suffered from ghosting i can say thats as good ad nonexcistant on this one(never saw it myself).
I really recommend an zero dead pixel guarantee to go with the monitor though i got it with mine and replaced it twice for free for one dead pixel
