That depends on what your uses are. It also depends on how close you are to the monitor. In my opinion just stick to name brands, the AOC I got from Circuit City last year is already partly busted(power button doesn't work, still able to turn on).
Thanks some good ideas i suppose i use my monitor for playing older games, word processing and the internet. So there really is no need for a high end monitor. I should have added that my GPU is an 8600 GT
