FX-9590 A List of Motherboards That Fit FX-9590

Yes I just saw that. Interesting.
They say that the 9590 is just the same chip with a higher clock speed. So it would run on the board if that is the case. Just lazy on MSI's part not to update their list.

So we are back to the gamers again I guess. No easy reasons here!

Are you running BIOS 22.2?

I think you are OK on the hardware side, so long as heat is not an issue.

I'm guessing that you may need to make some adjustments to your graphics settings. But peeps that game all the time would know better about that than me.
