How important do you think it is for a laptop to have a dedicated video card?

Short answer: it depends on what you want to do. For everyday use (browser, office apps, coding, video conferencing) a modern integrated GPU keeps the laptop thinner, quieter, cheaper, and longer on battery. For high‑end gaming, VR, heavy 3D work, or GPU‑accelerated compute (training models, CUDA/OpenCL pipelines), a discrete GPU or an external GPU enclosure is worth the extra cost and power draw. This mirrors the practical points raised by , and , but with more context.

Integrated GPUs have improved a lot since 2017 and can handle light gaming and many creative tasks on thin laptops. Intel’s Iris Xe targets smooth 1080p experiences and stronger media/AI assist features, and Apple’s M‑series SoCs put unusually strong integrated GPU performance into their MacBooks — both make integrated machines practical for many users. (intel.com)

A discrete GPU is the right choice when you need raw rasterization performance, more VRAM, hardware encoders, or access to specific compute ecosystems. If your workflow relies on NVIDIA’s CUDA software stack, an NVIDIA GPU is effectively mandatory for best compatibility and performance. On Linux, hybrid setups (integrated + discrete) often require extra driver/config work and can be a dealbreaker unless you verify support first. (docs.nvidia.com)

If you want portability now and desktop‑class graphics later, external GPU (eGPU/eGFX) enclosures over Thunderbolt are a viable compromise — they let a light laptop act like a workstation when docked, but check the Thunderbolt/eGFX compatibility matrix, enclosure power, and OS support before buying. (thunderbolttechnology.net)

Quick buying checklist: 1) list your real workloads (games, rendering, CUDA, editing); 2) verify driver and Linux support for the exact laptop/GPU combo if you plan to run Linux; 3) weigh battery/thermal tradeoffs vs. performance; 4) consider eGPU if you need occasional desktop GPU power.

I've never had one with a dedicated video card but I don't see this as a biggie. I can't imagine that you could upgrade the video card in a laptop and, to me, that seems the only reason to have a separate card. Incidentally, that's the reason my son's next gaming system will be a desktop/tower rather than a laptop.

If you want to play 3d games or develop with Cuda/OpenCL, very. For browsing the web and 'normal' development, not so much.

Neither my MBP and XPS have one, both are lightweight and quiet, and both cope fine with a big external monitor.

Also, if you plan on running Linux on your laptop, drivers become an issue. Especially if your machine supports switching between onboard and GPU modes.

It depends is the correct answer I think. For systems with Intel processors, there is a built-in Intel GPU that these days is pretty good from the performance perspective. If you don't need the highest performance graphics (top-end gaming, video processing, etc) then a dedicated GPU such as an nVidia card is overkill.
