Standard 1GbE networking tops out around 125 MB/s in practice — slower than a single SATA SSD, let alone NVMe. 10GbE raises that ceiling to roughly 1.1–1.25 GB/s, and it only matters if something on your network is actually capable of moving data that fast in the first place.
A 1GbE link is the bottleneck the moment your workflow needs to move more than about 100–120 MB/s over the network — which sounds like a lot until you're editing 4K/8K footage off a shared NAS, syncing large render outputs between machines, or backing up a workstation's full NVMe drive on a schedule. In every one of those cases, the drives on both ends are already faster than 1GbE can carry, so the network — not the storage — becomes the slow part of the pipeline.
If your work is mostly local — files live and are edited on the same machine, with the network used for occasional transfers or general internet/office use — 1GbE genuinely isn't a bottleneck, and 10GbE is money spent on a ceiling you're not hitting. The upgrade only pays off when the network is provably the slowest link in an actual daily workflow, not as a default "future-proofing" purchase.
A 10GbE network interface card on one machine does nothing on its own — the switch, the NAS/server on the other end, and the cabling all need to support 10GbE too, or the connection negotiates down to whatever the slowest device allows. It's a whole-path upgrade, not a single-component one; worth confirming the rest of the chain before speccing it into a single workstation.
ProStation builds spec networking to match the actual workflow rather than defaulting to the highest number available — relevant for storage/backup-heavy setups and virtualization hosts especially.
