Not quite yet. Text isn't very legible.
11 pixels per degree is what you see get by looking through the Rift Dev Kit 2
19 pixels per degree will be what to expect from a theoretical 4K Rift with Field of View like the Dev Kit 2
48 Pixels per degree will be close to what you see looking at a 24" 1080p monitor
So you'd probably need at least an 8K display to get close to the quality of a monitor.
