New System Build, any Suggestions?

Recommended Posts


now that I have seen some videos of Spaceinvader One and read a lot on the pages here...


The question is which board and processor should I buy to reach my goals?


Since the financial means are limited, the desired processor is already almost certain. It should be a: Ryzen 7 2700.


2 or 3 graphics cards are Avail and could / should be used, in conjunction with 3 VM's but only a maximum of two of them will run  the same Time.


1. an NVIDIA RTX 2060 Super
should be used for the Gaming PC VM.


2. a Radeon R9 280x
for a MacOS Catalina VM.


3. an Nvidia GT630 1GB
for an Allways ON - Windows 10 machine for surfing the net and similar
alternatively a Linux desktop instead of Windows 10.


The Mainboard should have as many SATA connectors as possible to complement or eliminate the currently used LSI controller.


Does anyone have a suggestion or experience with which board this is possible?


Thanks a lot
Greetings Hannes

The problem with the AM4 platform is a lack of PCI-E lanes to support what you want. 


There are boards that can support dual x8 GPU and a third in the chipset @ x4 but this shares lanes with other ports and possibly m.2 drives.


You are then limited  to the 6/8 onboard SATA which fill up quick with cache and parity.


If you can manage with 2 GPU then you can use an 8 channel LSI card on the x4 slot which will support 8x additional HDD.


I don't know how well MacOS runs on AMD so you might want to look at that.


As an alternative, 10 and 12 core Xeons such as E5-2660, 2680, 2690 are now priced eur100 to eur200 used and work fine in x99 motherboards with lots of PCI-E. These can often be picked up around eur100 used. Only issue for gaming is boost clock speed around 3.3Ghz which may impact of your looking for high FPS.

Thank you for this very detailed Information, i dont have fully understood this for weeks. but after weeks of checking testing reading and crying... i makes really sense now. i have shrinked my 'project vision' down to 1 GPU and upgraded the processor to a Ryzen 7 3700X but made a big mistake i bought a X470 Taichi ... nice mainboard but big mistake for me.

I run into huge problems... Running the RTX 2060 Super along with LSI Controller works fine and passthrough works fine. But then i would also passthrough one of the onboard USB controllers. Everytime it ends in a Server crash. So i bought a separate usb card and run into other problems. I think this problems is the "lack of PCI-E lanes" i have changed every possible position of slots but allways end up the same IOMMU group and this group looks like is not splitable and i cant isolate this card.

So today i have ordered a another board.. a Gigabyte X570 Aorus Pro as used in other threads here and send the Taichi back.


Thank you Again
