can it be mined using regular computer with nvidia gpu, will it be worth it or burn more power thn it can be produce a coin ?
You can't mine Zcash (and similar) with nvidia. This miner is AMD only, for nvidia you should take a look at EWBF miner or dstm miner.
Cheers.
For Equihash on my Nvidia cards I used EWBF. ZClassic is probably the most profitable still. Been mining it for several weeks now.
