I havent had them long, but performance wise its a massive step up from all my previous cards.
However at the moment Im experiencing slighjt freezes accompanied by an audio buzz when in games or videos, but its probably driver related.
Also am having a weird issue where my desktop artifacts like craZy, or not neccasarily artifacts, but all my windows try to jump in and out and half triangles of the windows will go missing/appear everywhere.
Once again most likely drivers.
As far as performance goes, these things are insane. If I can just get these problems nailed down everything will be great
