I will be buying a new monitor in the next week or so.  I will buy it from Best Buy because I have a gift card from there.   I want a good,but not crazy expensive one.  I know that 5ms response time is good, but is 2ms response time that much better?  Would I really notice the difference.  Also, are there any brands to avoid?  

Thanks.

ETA: How does this monitor look? Dell 20
