Hi
I whish to build an machine to use as NAS, TV Tuner and Game Machine at the same time. The GFX Board, Tuner Cards and USB controller should be passed to their respective VMs via IOMMU
Everything would under ESXi as hypervisor.

I have read a lot about AMD AM3+ and FX2 motherboards but I have still not found the perfect one.

I would need:
3 PCIe slots
2 PCI Slots
At least 3 USB 3.0 ports
Support for 32GB RAM

One of the PCIe ports would be occupied by IBM 1055 SAS/SATA controller.
2 PCI slots will have a SAT TV and DIGITAL DVBT boards.
The remaining PCIe Slots would a one or 2 GFX Boards

CPU power consumption is important to me. I still have not choosen the processor. a 65w TDP one would be good but also a 95w TDP would be usable. Nothing more that this value.

Which motherboard would you suggest which has less problems with iommu and ESXi 6.x ?

There is a 970 board which comes close but has 1 less pcie slot then you would need. Try and google it but I'm not to sure that it will fit your needs as in IOMMU performance google that one as well the mainboard is: Gigabyte 970A UD3p Revision 2
 
I have 2 Asus Sabertooth R2.0 that do IOMMU, enabled in BIOS

dmesg | grep IOMMU
[ 1.228616] AMD-Vi: Found IOMMU at 0000:00:00.2 cap 0x40
[ 47.072681] vboxpci: IOMMU found
[ 240.757355] vboxpci: created IOMMU domain ffff8803f88d5140

One is new-like in box, I'd sell for ~$100
