Power requirements: Always check the power needs of a card against your power supply's output. Don't forget to take the other cards and devices in your system into account concerning power usage. The most powerful GPU on the planet won't make a difference if your CPU is the bottleneck (and vice versa) -- think overkill. You'll see a lot of price variation across cards using the same GPU. That's for features such as overclocking, better cooling systems or flashy (literally) designs.  Dual-card setups are usually more of a pain than they're worth. Video editing is usually the exception, depending upon application support. If you want a card for content creation, game benchmarks aren't usually representative. To research those, start by running a search on "workstation GPUs" or, for example, "best GPU for Premiere." It's important to match the GPU to the application, because, for instance, Nvidia RTX A-series GPUs (the workstation GPUs formerly known as Quadro) are generally more powerful than their AMD Radeon Pro or WX series equivalents, but application developers who are tight with CNET_TAG: Apple | Score: 600 " data-slug="apple" data-subtype="" style="font-size: 14px;">Apple  -- which doesn't support Nvidia GPUs -- optimize their applications for AMD GPUs. The biggest example of this is Blackmagic Design's DaVinci Resolve video editor. For photo editing, it may no longer suffice to use a low-end or middling graphics card, though it depends on your software. With the latest generations of Photoshop and Lightroom, Adobe has begun to expand its use of AI-related technologies in meaningful ways. For instance, Photoshop's Replace Sky and Neural Filters can take advantage of GPU hardware designed to accelerate AI to speed them up, such as the Tensor cores in Nvidia's RTX cards. But if you don't have at least 32GB of memory, graphics applications may get a bigger boost from upgrading that before the GPU, unless the graphics card is really old.  For video editing, the amount of memory on the card can have a big impact on real-time performance as you work with higher-resolution video (4K and up).  Running games at 4K requires significantly more video memory than 1440p or lower, at least 8GB.
