An important distinction is that most of the features of these performance graphics cards are not going to be used at all with typical ham applications. Almost nothing in the ham application use 3D graphics. Instead, it's the 2D rendering performance that is key but it's not talked about at all in most card reviews. This is especially important because there is a complete and total mess in the higher end graphics market now which may confused and scare away hams from picking up a very fine graphics card that would meet their needs.
Fortunately there is a web page that will help guide relative speeds of graphic cards, both old and newer ones.

Take note at the G2D column, and sort from highest to lowest. Then just go down that list and check whatever graphic card you have an interest in.
Notice that the fastest card on the list is about 1000 in the 2D speed. The card I have in my main PC (GTX 1060) scores 770 - a card that must be at least 5 years old. It runs a trio of UHD monitors here in the shack. And you can get a similar one for under $100 on ebay.
I'm not advocating this card, rather mentioning that whatever card you are thinking of buying can be judged on it's speed by consulting this list. And anything that's on the top half (500 or more) will most certainly be completely fine for ham applications.
+ It would be nice to have a "Selecting a Video Card" article in the DXLab Wiki to go with the "Selecting a Monitor" article developed by Dave W6DE:

+ The above guidance regarding 2-dimensional rendering performance would certainly be included in "Selecting a Video Card", but there are additional considerations:
- resolution
- refresh rate
- power consumption
- physical size
- monitor connectivity (HDMI, DisplayPort, etc.)
- motherboard compatibility
+ Would someone like to take a crack at this?

I've followed this thread with some interest. It seems to me that an
important feature of computer, monitor, and graphics cards purchases is
missing.

I believe one should attempt purchases that reflect more what demands on
these devices are likely to be in the future than what they might be in
the present. While the future is unknown, it seems very likely that
demands for more memory, more sophisticated and faster processors will be
the future as they have been in the past. High-end graphics cards are a
requirement in the AI world we'll be living in well before you will want
to retire today's computer purchase.

Even if you can afford a computer used exclusively for amateur radio you
are likely to benefit from buying the? most powerful hardware you can
afford rather than buying what's needed for using the software hams are
using today.

+ That's a slippery slope:
1. It's not clear that high-end graphics cards will be a requirement for using AI. Yes, the development and training of Large Language Models (LLMs) currently involves the heavy use of graphics processing units (GPUs) because GPUs can rapidly execute the matrix multiplication operations employed in neural networks. However, exploiting LLMs - which is what hams would likely do - does not require such computation. Furthermore, the DeepSeek LLM demonstrates that the race for market share led many LLM developers to forgo optimizations that enable training with significantly less computation.
2. With respect to CPUs, plotting available CPU models on a price vs. performance graph generally reveals a suite spot. At the high end, paying an extra 25% to get 10% more performance makes little sense.? Larger CPU caches are worthwhile. More CPU cores will definitely make DXLab applications run faster. As described in the "Hardware Capabilities" section of

SpotCollector alone can make good use of 3 cores. One core for each additional application you expect to consume CPU cycles in parallel is a reasonable rule of thumb. Don't count the DXLab Launcher, as it only consumes significant cycles during upgrades. You won't need 256 cores unless you're going into weather forecasting.
3. With respect to RAM, more is always better. While 32 GB may be more than sufficient today, a motherboard with 32GB that is expandible to 64GB when you need it would be preferable.
4. Secondary storage - whether solid state or rotating - is easy to expand as your needs evolve. The 4 terabyte rotating drive I use for local backup connects to my laptop via USB 3.2 and cost $112! No, it won't meet my needs if I start DXing for dark matter and begin recording and analyzing data from radio telescopes, but likely other upgrades will be required if I head in that direction.
