A high quality monitor and a controller you don't even like isn't going to make you a gaming god, as it were.
Stick with what you have, or get a decent computer monitor. You can get ones with very low latency for around £100-180.
Computer monitors do tend to have a much lower latency (console output to display delay) but to be honest, I don't notice much difference between my 2MS delay AOC monitor, and my 22" Sasmung LED TV.
As I said, having the gear won't make you a god at gaming. It may help, but it's almost a complete waste of money if you're just a casual, or even a 'semi hardcore' gamer.
Going back to a point I made earlier on, why on earth would you consider buying something that you don't even like!?
