DigiTimes, citing "sources from the upstream supply chain", is reporting an expected decrease in graphics card pricing for July. This move comes as a way for suppliers to reduce the inventory previously piled in expectation of continued demand from cryptocurrency miners and gamers in general. It's the economic system at work, with its strengths and weaknesses: now that demand has waned, somewhat speculative price increases of yore are being axed by suppliers to spur demand. This also acts as a countermeasure to an eventual flow of graphics cards from ceasing-to-be miners to the second-hand market, which would further place a negative stress on retailers' products.
Alongside this expected 20% retail price drop for graphics cards, revenue estimates for major semiconductor manufacturer TSMC and its partners is being revised towards lower than previously-projected values, as demand for graphics and ASIC chips is further reduced. DigiTimes' sources say that the worldwide graphics card market now has an inventory of several million units that is being found hard to move (perhaps because the products are already ancient in the usual hardware tech timeframes), and that Nvidia has around a million GPUs still pending logistical distribution. Almost as an afterthought, DigiTimes also adds that NVIDIA has decided to postpone launch of their next-gen products (both 12 nm and then, forcibly, 7 nm) until supply returns to safe levels.
To interpret: The cryptocurrency craze is over and there are now too many GPUs out there so Nvidia won't release anything new until existing stocks have been reduced and there will soon be a glut of ex mining cards on the used market.
By all means build the system, it's a very strong one, but get the GPU last of all and if you DO find a ex mining card going for a song on E-bay ( or similar ) don't be too afraid; coolers and fans can be replaced and any card that has survived mining is likely to be a true survivor.
