Amazon has LG 34UC79G-B 34-Inch 21:9 Curved UltraWide IPS Gaming Monitor with 144Hz Refresh Rate for $494.90 no tax free shipping. Get 5% cash back with Discover or Amazon Prim Credit card and make it $470. If you have double cash on your Discover card like I do, then you would be practically spending $445 for this monitor which is a pretty nice deal.
This is one of the best rated ultrawide gaming monitor on the market. Even though it's not 1440p. But with 144hz refresh rate and curved IPS panel. It would provide some really good gaming experience.
