I'd like to build a workstation with a minimum of 6 1080p screens. The GTX 1050 Ti has a max resolution of 7680x4320; this should suffice for future upgrades.
If we're splitting the workloads by the 80-20 rule:
80%: Confined to web browsing, potentially offline office applications (MS word, electron apps like Slack). The intention is to keep many tabs open, so this may be a consideration if hardware acceleration is of significant enough benefit to warrant a better GPU. Unlikely to have more than a single active youtube video at a time, though likely a fair few cached / in suspended processes. Video calls are quite likely, though I'm under the impression encoders/decoders are their own circuits that don't compete with other functions.
20%: 1-2 instances of a LaTeX editor, MATLAB or Python open; a mix of data visualisation, numerical analysis or agent based simulations.
Monitors: The plan is for an arrangement similar to the financial rigs at Optiver. Depending on cost-effectiveness, I may move to having fewer screens of higher resolutions. I'm not averse to the dual graphics cards, however the price increases in computer hardware have been disportionately larger amongst GPUs. I'm unsure how concerned I should be of supply availability.
