Hello, I was wondering how many hashes per second, the AMD Radeon R7 240 and NVIDIA GEFORCE GTX1060 produces on the following coins:
Ethereum
Zcash
Monero
Litecoin

LTC hasn't been profitable for GPU mining for years since scrypt minig was taken over by ASIC's. The R7 240 is only 2GB, so it won't work for ETH. The 1060 should get ~25 MH/s on ETH and ~300 H/s on ZEC.

The computer I am looking to purchase has this as the title
"Exper EXP-XC250 Xcellerator Gaming Intel Core I5-6402P-2.8Ghz Processor, 16Gb RAM, 1Tb Hdd, 4Gb GPU Windows 10 OS"

In the features table, it says that the GPU has 4 GB

The R7 290 is a DDR3 card, so I doubt it would be very efficient at mining Ethash, which is a memory intensive algorithm. There is a R7 290X card that has DDR5 memory and supposedly gets ~15 MH/s. ZEC would probably be a better option for that card.

IMO, you would be better off going with a RX 560 or 1050 Ti cards, that get ~14 MH/s on ETH and are much more power efficient.
