Thanks for your suggestions.
I'm glad I asked, I wasn't considering altcoin mining at all.
@newmz I didn't know at all about the Baikal CUBE units. The front costs is to much for me at the moment. i only have 300-350 and prefer to buy a graphic card. Also have a spare computer on which I can put the graphic cards.
@Cereberus NiceHash mining software looks like a very convenient and easy way. I'll probably use it.
@Vaccinus @JaredKaragen @Cereberus I already have a spare computer with 1x PCIe 2.0 x16 and 3x PCIe 2.0 x1. I just need a graphic card. I'll probably start with one or two RX480, they're cheep and mine well.
a gtx 1060 is a good alternative to amd, it's on par with a 470 on other algo, not ethereum, people need to learn that there are better coin than ethereum, but amd is good for dual mining i see this as the onyl reason to go for amd, otherwise always nvidia, zcash and lbry is also strong now
