Samsung in general makes a good monitor. I would not have any reservations about buying one of their PC monitors. Just make sure you get the best price possible, at a good resolution.
That SAMSUNG 2253BW looks like a good gaming monitor with its 2ms response time. And 8000:1 contrast ratio isnt' to bad.
The T220 suggested above, is pretty sweet looking with its 20,000:1 contrast ratio. That thing should have some stunning black/whites & colors. It also has the same 2ms response time.
Considering the prices are pretty close on NewEgg.com, I'd go for the T220.
Depending on your budget:
Samsung T220HD (Has HDMI, 1080p HD Tuner built in).http://www.newegg.com/Product/Product.aspx?Item=N82E16824001278
Little more expensive, and has a 5ms response time instead of 2ms, and 10,000:1 contrast. But you'd have the HDMI and 1080p option.
