Hello, i know this might have been asked before but i couldn't find an answer.
I want to get into mining, where i live electricity is quite cheap (about 0.05$ per kW), i'd just like to ask a few questions before starting to think of a rig assembly plan, im planning to mine eth or zcash, depending on what's better at the time.
1) Does an SSD matter in mining? would a cheap hdd lying around do the trick?
2)If i'm mining with 3-4 GPUs, would a h81 btc motherboard be necessary?
3) I know that the current most efficient GPUs are probably rx 470 and 4x 480, but i'm getting confused messages about which is better and is 8gb cards worth the extra dollars? Also what company is better for mining XFX, powercolor, sapphire, does it actually matter?
and lastly what are risers for?
Thanks for the help.
1) SSD does not help at all, go for cheap hdd
2) H81 would not be necessary for 3-4 gpus as long as you have motherboard that supports them
3) Zcash will die and Nvidia is currently only good at zcash. Go for AMD, best card overall now is RX 470. If you get that you cannot be wrong
