Security now on that Twit network covered this. All of this is on the third party chip set; that AMD is paying a Taiwan company to make for them. And it sounded like this company did a bad job making these chips. One of the vulnerabilities was a hardware backdoor of some kind and it sounded like the hardest to fix. Sounds a lot like the issues Intel had with their chips.
I regret not going 4k or 1440p when i got my new monitor last year. I see all the pixels on 1080p. The Anti Aliasing is weak.
My Acer predator is 1080p 144hz G-Sync and 3D Vision. Other than I wish i went higher than 1080 It's a great screen. The 3D was even fun for a little bit.
Though it was like 600 usd.
