Want to get a 5090 but found the price to be a bit outrageous. The GPU's VRAM cost is soaring, mainly due to supply restrictions on high-end AI chips—after Nvidia's flagship product was disabled, computing demand has surged into the consumer graphics card market. As a flagship mining tool, the 5090 is in short supply, and this situation is unlikely to ease in the short term. For miners, the rising hardware costs directly reduce mining profit margins. This price increase cycle may last for a while, so be sure to calculate the ROI carefully before purchasing.
