Look up multiple reviews and benchmarks from all different sources before making your decision. Some apps, such as Final Cut Pro, directly choose which graphics processors are used and will ignore the Prefer External GPU checkbox. If you mean, as I suspect, two GPUs per laptop it depends on the laptop and GPU and eGPU solution - but probably not, and if you could it wouldn’t help you much. Don't just start a thread and take the word of someone on a forum/reddit thread. First of all, if you mean one external GPU for each laptop, then yes, if the laptop supports an eGPU solution (external PCIe adapter) that you can find.
Assuming a modern Intel or AMD CPU? A very general rule of thumb is:ġ440P at high frames or 4K = Top Tier Cards.ġ440P at 60fps or 1080P at high frames = Mid Range Cards.ġ080P at high frames on older games, or lower resolutions = Lower Tier CardsĪs always, it's best to do your research first.
The procedure looks simple enough and the results are impressive I stumbled across this DYI review of a 50 USD device that allows people to use an external graphics card from a PC on a notebook. This answer is also dependent on the CPU you have. Stephan Deutsch ran into this review of an external graphics card adapter that can blow new life into your old laptop. What card you should buy depends on the resolution and refresh rate of your monitor. When choosing between a high performing older card and a mid range similar performance current generation card, it's always better to go with the newest card. When faced with the choice of two lower cards in SLI/Crossfire over one single better performing card, the single card is always the better option.
