Dell U2717D input lag for gaming?

[BFG10K]

I’ve seen multiple reviews that state it has high input lag, but other reports say later revisions have fixed the issue.

Anyone using this monitor for gaming, especially for FPSes? How does it compare to other 60Hz panels you’ve used, and when did you buy it?

Please, no comments about 144Hz, etc. I just want to hear about this specific monitor, thanks.
