In January I was looking to buy AMD graphics card(s) for numerical work using OpenCL. That time (roughly) corresponded to the peak in Litecoin prices. The best card - 7990 was generally sold out, and was going for about £600 on ebay. Since then, Litecoin has dropped massively in value [1], and I am seeing sellers offloading eg "16 GPU cards + mining rig" on ebay. 7990 cards are now selling at around £300. There might be other factors at play - eg the newer (and slightly better) R9 290X, or the anticipated arrival of dedicated Litecoin miners [2] - but mainly I think it is the price drop.
