Budget ?
The best gaming experience available today is on the 17" 165Hz IPS panels made by AU Optronics. You can find the 8 bit color one on the Asus PG279Q ($750) and the 10 bit color one on the Aver XB271HU ($700). Dropping down to a TN panel, you could get a PG278Q ($620) or an Acer XB241YU ($500)
