Want to upgrade my miner, GPU compability question

[Freeman87]

Hello everyone,

as the title says id like to upgrad my old miner. Or better turn my old computer into a miner. Im using asrock pro btc together with a r9 290 sapphire. Now i got my hands on a msi r9 390 8gb gaming that solely runs at 30kh.
What im wondering is
(1)if i can run them together?
(2)what 2 cards i should buy to round up. Can i buy 2 470 8gb and run them along the r9 290 and r9 390? As the 390 would cost me quiet alot more.

Thanks for your help

1- Yes
2- Yes

It's a damn short answer, but that's it

Mixing generations like that will work if you use a driver version that supports both.

 It won't be as stable as a general rule though as sticking with same-generation cards.

 For reference, the HD 77xx/78xx/79xx, R9 2xx, and R9 3xx count as the same "generation" as they were all based largely on the same GPU from one "marketing generation" to the next with no more than a "faster ram and bios change between each "marketing generation".

Thanks for the clear answer! So what card would you personally go with? A 290/390 to stay the same generation or a 470/480 as they seem to be alot cheaper.

Im tending to upgrade with 2 470s
