http://ca.pcpartpicker.com/user/Canadian_Born/saved/#view=rb6J7Pthats my current gaming, photo/vid editing, music composition, dj rig.. does everything i need it to do..
I had the M5A 97 R2.0 motherboard, and found the 8320/8350 bottlenecks on the chipset, under extreme rendering. since upgrading to the M5A 99FX Pro R2; I havnt had an issue.
as my build shows, I am running a 2 way sli, and havnt had an issue with it, however ive had a few friends with the same motherboard complain about issues in 2 way sli with other manufacturers primarily evga, (i am running dual MSI Geforce gtx 980ti's)
in my opinion the m5a 99fx pro r2 is the most solid motherboard for the 8320/8390 cpu's; however; some would probably disagree
you can look into the sabertooth, or rampage as well if you wanted to opt for older chipsets
