One of my recent builds is running the AMD FX-4350 Quad-Core CPU and Windows 7 Pro 64.
And...the $79.99 price is excellent bang for your buck.
AH3 is using 2 cores and runs quite well.
Good Morning Drane, do you prefer to use your GPU/HDMI connection for Audio from the Video card, verses using the onboard sound from that MSI MB's Realtek Audio? just curious?
I have 2 different builds using the AMD FX-4350 CPU, and have not run into any issues on either build... matter of fact the build I use as my current gaming rig is using the FX-4350 on an ASUS M5A99FX PRO R2.0 MB using 32 GB of Crucial Ballistix 1600MHz DDR3 System Ram (4) 8 GB DIMMS with an AMD Radeon Sapphire Dual-X OC edition R9 270X 4GB GDDR5 256 bit

the other build is using the same MB that Drane is using ( this is my Dad's computer, I built for him ) running Windows 7 Ultimate SP1 64 bit
As for this CPU using multiple cores in AH3, the 2 I have built are using them.... back during /near the end of closed beta, I noticed that my rig was using all 4 cores interchangeably while at times using 2 cores here and there, switch across all of them... I was not assigning any affinity or prioritys manually for any cores, I just let windows 8.1 Pro do the scheduling/threading/IO, etc...
I like your Motherboard choice, VanceVP, I might have even chose it if it was available when I built this rig...
I would recommend you taking a look at getting either the Black WD Hard Drive if you want to stick with Western Digital........but I recommend you getting a Hitachi deskstar wit either 64 or 128 MB cache or if you can afford it a hitachi ultrastar enterprise drive with 128 MB cache......... you can go either SAS ( 12GB/s ) or SATA III ( 6GB/s ) with not very much difference in the cost... check them out on newwegg..... don't get anything under the 74000 and 76000 series of these HD's..... do your research
in any case, seen and heard about a lot of those WD Blue HD's failure rate
Hope This Helps and have fun building!
