An interesting set of data was compiled by WCCFTech today, with the site keeping a "very close eye" on the graphics card market over the last year or so. The site has looked at prices over the last month and noticed a huge drop on Amazon's price of both GeForce and Radeon graphics cards.
It was only back in January that an NVIDIA GeForce GTX 1080 Ti was $1600 and AMD's Radeon RX Vega 64 was $2100, but prices have been coming down slowly through February, and much faster into March with sharp declines between March 27 leading into today.
Starting out on March 5, the price of an XFX Radeon RX Vega 64 was $1400 and has dropped drastically back to down $945 on March 27.
MSI's GeForce GTX 1070 Ti Titanium graphics card was hovering at around $789 on March 2, and then saw a huge drop to $629 on March 29.
On the mid-range AMD side, the XFX Radeon RX 580 GTS XXX Edition was $470 on March 5, dropping down to $389 on April 4.
