I’ve doing a bit of searching, but couldn’t seem to find anything similar.
Apologies if my search fu is bad
Just to give a lil something about where I’m coming from:
Currently I have an FX8350, Crosshair V Formula-Z, some 16Gb 2400MHz DDR3 RAM, a HD7790 for Debian host running KVM with a R9 290X passed through to a Windows gaming VM.
I would like (at least in the beginning) to use both GPUs in a similar, but more modern, setup. Either Ryzen 7 2700x (and most likely a Crosshair Hero VII) or some form of Threadripper (not decided on motherboard yet). Motherboard must be excellent in terms of IOMMU groups (and other goodies).
It has come to my attention, though, that the 2700x only comes with 20-24 PCIe lanes, compared to Threadrippers 60+ lanes.
Will most likely want to use 2 (if possible) nvme SSDs in the setup, with one with the Linux boot/system/root/perhaps more, and the other passed through to the Windows VM.
Already this setup seems to be at odds with the 2700x and PCIe lanes.
Additional PCIe cards might occur.
I would like for the PCIe to run full on version 3.0 and not downgrade itself to either x8 3.0 or x16 2.0.
Currently, my old arsed FX8350 setup is running full on x16 2.0 (max for the motherboard) on both GPUs at the same time.
Would it be insane to go for a threadripper setup (for example 2920x or something) (price wise), but get all the PCIe lanes (& other features, and possibly whatever issues there might be with threadripper ), or would the performance difference be neglible to non existent on a 2700x setup?
Budget wise, I can deal with up to a threadripper 2950X, some 32Gb of fast’ish RAM, and any of the threadripper motherboards.
Also, would threadrippers “game” mode be of any use for such a setup, or is it just for a full on Windows only installation?
Additional: Will also be streaming on twitch some of the games played, both on Linux and Windows, through OBS on whichever OS I play on.
Any constructive or informational feedback is appreciated.
