Looking into building a rig for mining XMR ect. What are the best GPU's for that right now?
Thanks for the help and this should help newbies in there research as well. Also I'm not looking for necessarily energy efficiency more hash power I know 290s are good but price wise better to get 280s and run them in crossfire or sli?

280x and 290 are definitely the way to go. 290 is a slight performance increase but the 280x costs less. If you get the right 290 you can flash the firmware and run your 290 as a 290X which will give a marginal increase. But the newer 300 series are not worth it, they cost more for the same hash power. If you can get your hands on some used 7970s at a good price they are about the same as the 280x. They provide a little less hash power, but they cost less as well. The difference between the 7970 and 280x is about the same as the difference between the 280x and the 290. If Energy efficiency isn't your concern you could look at some older 6990 or 7990 dual GPUs, but they're harder to find And whatever you do, don't run them in Crossfire, that will only hurt their performance mining.

Thanks, so sli is fine as there all running independently correct? I've only ran one GPU so upscaling now.

You won't be able to put the cards into SLI if you have AMD cards (which is the 280x/290 product line). For mining the best thing to do is run each card independently. You would just install them like any other graphics card and then not go through with the setup for Crossfire. If you're using Windows it should have no problem detecting multiple graphics cards.

280x for ethereum of 370x but i actually prefer 970 for everything else, and for ethereum it's not so bad either, i like low consumption

For Ethereum, R9 380 can get you 20MH/s. Do you have the 2GB version? 2GB should be slower than 4GB in the future.

But you should be able to reach 22-23 MH/s on an R9 380. If you're comfortable with firmware flashing you could attempt to flash it to 380X firmware, it might give you a a small performance increase. I did this with my R9 290 and saw a a small increase Also good you got the 4 GB version because 2GB cards will not be able to mine for much longer (some people have reported already they can't mine with a 2GB card)

But i can get more of these if anyone is interested..?

You can flash it using the modified BIOS. When You need to RMA, you can flash back. You card should not be too dead to flash.

If it's dead, how can they know the bios as been flashed?

They will have special tools to revive the card. After they make the card alive, they will know if that has been flashed.

You should be able to google up good guides on how to flash the BIOS of AMD 280X/7970 and 280/7950 cards, and even 290 reference cards. For newer AMD cards it is more difficult, although somebody just posted a way to undervolt the Sapphire R9 Nano card.. I am looking for a way to undervolt my R9 380X card by BIOS mod, but havent found anything that works yet. Tried the Hedzin BIOS reader, but that wouldnt recognize my Sapphire Nitro 380X card..

Do you know a why to mod the XFX R9 390 cards? They consumes a lot of energy, so it is beneficial to reduce voltage.
