Like absic said ,there should be no issue upgrading.
I have version 1.0 of the board and it worked to upgrade from F3 to F5.My board is version 1.0.
Mine is already back in it s box ,after one and a half year of usage , due to the good experiences i ve had with it.
I recommend you to use BIOS-es one at a time and not to jump to the last , as all of them have random issues either with USB 3.0 controller, either with the SATA controller,either with CPU throttling or with memory compatibility.
So upgrade to F5 ,install the CPU and observe what happens.If with F5 you have issues running Steam games go for F6
Then, if you encounter issues go for F7 and so on.
Keep in mind BIOS support is slow and compatibility seems to be strange with FX CPU-s for versions under 3.0.
