That's because you got the A2 (i.e. 2.0) version. Lots of dissatisfied owners of the K9A Platinum.
I haven't seen any dissatisfied owners.
There were 'issues' like with any other mobo. Since it is a sb650 it has no ACC (which equals no unlocking). The NB/IMC tweaking had a lot to be desired in later BIOS releases but if that was critical you could always revert to an earlier version. I never tried (should have) AHCI - especially the 'port multiplier' - on the eSATA so it may have been borked.
And the stand-offs for the mobo headers were a little funky - LOL
With the question of relevance of motherboards the MSI simply flies in the face of the OP. I like ECS, Biostar, et. al., but their mobos suffer from a lack of on-going support which really makes them irrelevant from an enthusiasts standpoint - unless you like to change mobos as often as you change your drawers.
And of course, some motherboards are always the exception beyond the norm --- the MSI 790FX just happened to work out that way with the DDR2/DDR3 IMCs of the AMD procs. Throw in 2+ years of BIOS updates and it runs most every desktop cpu made over the last 4 years - not including some Optys that it will run.
