According to Digitimes (paywall, via Tom's Hardware), skyrocketing copper prices are the next big challenge for the graphics card and motherboard manufacturing industries. 

Almost all electrical devices rely on copper and copper foil as components because of the extraordinarily high conductivity that the metal has to offer. Copper and copper foil are therefore vital components. It is anticipated that the higher pricing will have a particularly negative impact on the lower-priced segments of computer hardware.

From USD 7755 per tonne at the end of last year to USD 9262 per tonne this week, the price of copper has increased by about 20% in the first half of this year. PCBs (printed circuit boards, abbreviated as pcbs) are made up primarily of layers of copper foil, and graphic cards and motherboards are, in essence, large and advanced printed circuit boards. Copper-related parts are particularly important in graphics cards and motherboards, which require a large number of copper-related parts. Copper is also commonly utilized in heat transmission applications, such as within a graphics processing unit (GPU) or as the primary component of a CPU cooler. Lower-cost motherboards and graphics cards would be particularly hard hit by the higher manufacturing costs resulting from the present copper price situation. Premium models are currently still sold for sky-high prices, while entry-level models are sold for around the suggested retail price. It follows that price rises are possible, particularly in the lower sector, given that producers do indeed pass on the increased manufacturing costs to consumers.
