It's come a long way, but I still use Afterburner. And here is why.
It really comes down to the OSD. It needs to be able to do what Afterburner can. I have CPU/GPU usage on my taskbar icons. Precision X1 can't do CPU usage for some reason. And the tray icons are low quality.
The OSD itself is also lacking quality and advanced options. Also still cannot do CPU usage.
I would be all over using Precision X1. But in terms of overall features, UI, OSD, and general usability it still has a long way to go.
Honestly I would be happy with a reskin of Afterburner tuner for EVGA cards, but I understand that's not likely to happen.
