Well, it is true. This weekend, I was searching online and I visited a few tech shops near my place to get a Titan Xp. Originally it is for $1200. But the market was fluctuating badly and people were asking for a maximum of $1450 due to its unavailability.
The guy, who I purchased from happens to be a good friend of mine too, he suggested that the prices of parts and whole PC rigs will go up now in a few months time. PC demand is in boom and the products are not supplied as much as the demand is.
And the rest, technology is improving and is so is the cost and so are the prices.
