Hello, guys 
- I am new in mining and I wanna start with Zcash. I wanna use single GPU to start, and I wanna chose between Radeon RX 480 OR Radeon R9 280 or 290 - I need your advice and ideas. 
Will it be beneficial with single GPU?
And how much H/s I can get with the cards I mention above? (any close idea?)
thanks

480 will be MUCH more power efficient. dont get a 280/380. a 280x/290 will be the best $ per sol/s for now. 390 is like a 290, but better (IMO). but not better on price. I'd say get a 480 with civ 6, that would be the best deal for the long run. check out my site if you need info of all kinds on crypto mining ! Up to you, but keep in mind 280x and 290s werent doing much profit 2 months ago because they are power hungry, but right now they are doing profit.
