With an older i7-3770K and a new 980Ti, I recently went from a 24" 1920x1200 to a new Dell U3425W at 3440X1440. Keeping the settings the same in 3.2, I saw no perceivable difference in frame rates (perhaps 3-4), but what you gain in visual immersion... wow! I was afraid I would have to get a new system (6700K) to push it, and while it would be faster, I am quite happy with the performance I currently get. On a side-note, adjusting to the Wide-Angle mode took some time, but there is no going back!
