Ich verwende seit Jahren nur noch MSI Boards. Aktuell für die AM4 PC`s immer das MEG X570 und vorher für den Threadripper das 399x Creation. Ich war/bin mit den Produkten immer sehr zufrieden. Schön zu sehen, das sie jetzt Kundenorientiert reagieren.

Als sehr langjähriger Asus User/"Fan" und nach etlichen Enttäuschungen bezüglich Supportes bin ich auch dabei MSI zu testen und wurde bis jetzt nicht enttäuscht und bin bei manchen Sachen immer wieder positiv überrascht.
