I just checked on eBay, and there are multiple listings for single port 100 GbE Mellanox (now nVidia) Connect-X 4 cards in the $60-100 range.

Then you probably don't know about Spectre and Meltdown from a few years ago. Same family of problem on x86-64 (so Intel and AMD chips).
The presenter chats with Milo.
If you mainly want to "hide" your IP, you can't. Look at the headers of any message. It'll still show the original source IP, which will be yours.
For the rest of the time I'd recommend getting a spam filtering service. Mimecast, ProofPoint, Barracuda, etc.
Messages sent to you go to the filter, which then forwards the message over to your mail server. Outbound you configure your server to use the filter as a smart host. These filters will also buffer messages if your mail server is offline. So if the server is down, the filter holds on to messages and retries delivery later when your server is back up (within reason).
I don't recall in virt-manager off the top of my head. But if you make changes in the XML of a domain, you do have to shutdown/restart the domain before they're effective. And just to be safe, I would say to shutdown the domain, then check the XML, then start up again.
You do say you're just using qemu, so if that's the case and you aren't using libvirt in front of it, shutdown the VM, make sure your qemu command specifies an e1000 network device, and run again.
I can check virt-manager when I get some free time this evening, if that's what you want/need.
You may need to shut down the VM, check the device config to ensure it's set to e1000, then boot it back up. The PCI ID on your original post belongs to the virtio-net device.
Instead of trying to backport the virtio device drivers to that version, I'd recommend editing the VM to use the emulated e1000 NIC.
You must have had a real sweetheart deal on VMware then. Proxmox is cheaper than VMware even under the old pricing. You also don't have to buy the "Standard" subscription. There are cheaper ones.
When you see the Windows and Apple icons on a game, that indicates native Windows and MacOS support. The Steam logo is native SteamOS/Linux. You'll also see a "SteamOS/Linux" section on the system requirements.
I'm not aware of any that would run all of it at the same time. Most of this equipment is built for use with a server CPU and motherboard, which obviously has more PCI-E lanes. The Zen 5 consumer CPUs only have 28 PCI-E lanes, so unless you buy a motherboard that breaks out more through the use of a PCI-E switch, that's all you'll get.
They're replacing their in-house engine with Unity, so SI has actually been rebuilding the whole game in a new engine. From what's been going around, they ran into issues with Unity's UI tools.
