Well I currently have a MSI 890FXA-GD70 Motherboard. I decided to upgrade my 1090T to a 8350FX and grab myself a 750ti for my linux install freeing up my 280x for passthrough. Well come to find out there is a bios bug for this Motherboard and it will likely never be fixed. So basically I dumped $370 for nothing. After some research I have found that many have had less than desireable results on many 990FX motherboards. So, in an attempt not to get screwed again, and to prevent others from being screwed if you have successfully set up IOMMU on your rig please post your hardware specs. Thanks
