What is this Worth?

[Lord Letto]

Just wondering, but is there a good calculator for the formula? I'm currently looking for a socket 1155 board that allows overclocking for my i5-2500k but I think prices for them are too much, moreso for NOS parts ($355(asking price)+$20(shipping)+13%(sales tax) for a brand new board that (from what I could find after a quick search it cost $190 (+13% tax) back in 2012 (from where I found the price, was $150 after a $40 MIR at Canada Computers), the board I'm looking at is a ASRock Z77 Extreme4))

Edit: using a depreciation calculator I found using google, if the formula & information I entered is correct, then It would be worth about $38.27 in 2018 with a purchace price of $215 ($190+13%=$214.7) in 2012 correct? ($215 asset value new in 2012, 25% depreciation per annum over a period of 6 years (2018-2012=6))

I'm not sure that's how depreciation of commodity works, but here is a board for under 100 USD
