I have a more than 10 years old PC, but it is more than enough for me. Baldurs Gate 3 in 4k split screen is the current that I play with my GF.
FX8370 4,75GHz with 1,4V
Thermaltake 120mm AIO
Asus M5A99X evo R2.0
MSI GTX 1080 8GB
1TB Samsung EVO 860
512GB Kingston something
And my favs
4x16GB DDR3-1372 Dualrank(!!)
Fusion IO drive II 1,2TB PCI-e
2687MHz NB clock
The temps are under 1h OCCT 8 core AVX test.
Max when the case was with sidepanel, current is without sidepanel.
But 310w from the wall.
(CPU diode is the real cpu temp. The other one is the "socket" or something related.)
