I just decided to try gaming at an old age. I hadn't built my own rig for 7-8 years and this is the first time in my life buying such an expensive GPU. I know it wasn't the best decision to go with RTX 2080 but at the time I pre-ordered, brand new 1080ti was around the same price. I am going to use this machine for gaming, video editing and virtual machines. I am a bit old school and don't like liquid near electronics so no water cooling for me. I want to try with stock cooler first and might upgrade to a better one later on.
Update 28/09/2018 for temperature in case someone is interested. I still don't quite get how XFR2 and PB2 and Ryzen temperatures work.
Bios: DOCP RAM to 3200mhz and everything else is optimized default settings. CPU Cooler: AMD Wraith Prism stock cooler with original thermal paste
Room Temperature - 20c +/-0.5. Case panels closed. CPU temp read by Ryzen Master and GPU temp read by MSI Afterburner CPU idle - 32c-40c (sometimes jump to 47c momentarily - i think that's ryzen and XFR2 weird behaviour) GPU idle - 32c-35c
CPU Tests: ASUS RealBench Stress Test 15mins - All cores boosted to 4000mhz if temp is below 65c. Over 65c, all cores boosted up to 3900mhz only. max temp at 73c. Prime95 - small FFT 5 mins - all cores boosted to only 3775mhz - max temp 64c Prime95 - Blend 10 mins - all cores boosted to 4000mhz if temp below 65c. Over 65c, all cores boosted to only 3900mhz. max temp 72c.
GPU Test: MSI Kombustor 1440p test - GPU temp jumped straight to 80c in 2 minutes - aborted test immediately.
Game: Monster Hunter World - 1440p Highest Setting (fog off) 2.5 hours - GPU temp max at 72c 99% load(with GPU fan manually set at 80% speed). CPU temp max at 62c, all cores boosted to 4000mhz but only 30-50% used.
