First - The Setup
CPU: AMD FX-9590 Vishera
RAM: 64 GB
MB: ASUS SABERTOOTH 990FX R2.0
GPU: 2 - XFX Core Edition R9-295X-8QFA Radeon R9 295x2 8GB (Running In Crossfire)
Monitor: SAMSUNG UD590 Series U28D590D (Using DisplayPort 1.2) (Max Res: 3840 x 2160 (4k))
Catalyst Version: 14.12
OS: Win 8.1
When playing some newer games (Hero's Of The Storm, WoW, Borderlands Pre-Sequel) the game A.) Stutters (FPS drops dramatically) B.) Crashes (Either the game or reboots my PC)
I have tried using different connector from the video card to the monitor (DVI-HDMI) but Win 8.1 will only allow me to 1920 x 1080. (Even then the screen image doesn't fill the entire screen.)
My question is this a display driver issue, hardware (monitor or video card), OS, ??
(It's just frustrating that I cannot play a game on my new built PC without it crashing)
Thanks in advance for all suggestions.
