The price of all NVIDIA cards have seen a huge hike in price in the last few weeks due to availability. As such we recommend sticking to lower cards for the time such as the GTX 1050 as this hasn't risen as drastically.
NVIDIA have asked suppliers to restrict sales to 2 per customer so this may see a decline in the availability for miners, but this will still take a while to see any decrease in price.
As such our prices may be changing constantly as the purchase price is reflected in the end user price. As an example we have found that the GTYX 1060 6GB card has gone up by £120 in just the last few days. The GTX 1070 and 1080 are proving to be the biggest movers meaning that we are not stocking these cards at the moment.
