Great feedback and advice folks, it is much appreciated.
kksnowbear, thanks for crunching the numbers. I had done some math myself and was coming to the same conclusion about my set-up being able to handle the 1080p res, so your analysis makes me feel more confident in that conclusion.
Rick, I'd love to make the jump to 1440, but as noted above, my system just isn't going to be able to adequately keep up.
Stache, oh to have your set-up. It's still the cat's meow.
I'm leaning towards the LG 34UC89G-B 34-Inch 21:9 Curved IPS monitor with G-SYNC, which is currently available for $499 with free shipping. I have always had good success with the LG monitors, and this one has some impressive features for the price.
