I've been running a dual GPU system for a while now using Proxmox to assign each to its own Windows virtual machine.
This is working fine and I'm happy with the performance and convenience of it.

Now I want to add a 3rd GPU for another VM but my Strix X570-F is too small to take another and I would suffer from lack of PCI lanes.
I've seen Threadripper as an alternative but they seems unreasonably expensive. Is there another option I'm missing?
 
Having looked at my case (H9 Flow) a bit more I don't see many options without replacing it which I don't want to do as it's fairly new.
There's no space for a bigger board and there's not really much space for a 3rd GPU unless I started watercooling..
The current cards are a 3090 and a 1080Ti, I'd be happy to run a 3rd card with 4 lanes for now if I can get it to fit.

you wont get it to fit. reason being is that the 3rd x16 slot is in slot #7 (ie, bottom of the case and will only fit single slot cards)
if you don't want to go open bench, you will need to get a full tower with 8 pcie slots (midi towers only have 7) - so there will be room for a dual slot card

Fair enough. Building a 2nd rig is starting to look like the more sensible option.

i disagree? makes no sense whatsoever

all you need is a new case, or an open bench + risers
£100-200 vs £300-500 depending on the parts
and even if you do upgrade to the new platform, you *will* still need a new case to mount said gpus

how is that more sensible lol
(i'm also assuming your psu is of a high enough capacity to power the 3 gpus)

My current PSU should be able to take it.

You're changing my mind :) I'm looking at a Lian Li 011D now as I could put 1 GPU vertically on a riser leaving plenty of space for the other 2.
