I have been posting on the 2080ti thread because no one was in this one...
Things I can tell about my MSI 2070 Armor (530€ Portuguese store):
-It is very powered limited
-It has the non-A chip and it can not be flashed with other A chip bios, yet I hope.
-I tried an sort of did, shunt mod it and the OC wasn't great also... but more stable while benching.
-Flashed it with a non-A chip bios from EVGA and it messed up one DisplayPort (EVGA has a DVI) and also messed up the powerlimit... (will test again maybe.)
I am waiting for a possibility to flash with a A chip bios.
