Hello,

I have mining for a while now, scrypt, with 7950  (2 Sapphire + 2 MSI TF) now is the time to add 2 more.
Last time i was in this position the chose part it was easy = 7950.

Now it seem's hard, becouse of the space i have to stay on the R9 290x part  to achive the hash rate.

The aviabile card's are:

VIDEO SAPPHIRE ATI R9 290X 4GB DDR5 512 BIT 21226-00-53G  -  595usd
VIDEO ASUS ATI R9 290X 4GB GDDR5 R9290X-4GD5   - 594 usd
VIDEO SAPPHIRE ATI R9 290X 4GB GDDR5 21226-00-40G  - 585 USD
VIDEO GIGABYTE ATI R9 290X 4GB DDR5 R929XD5-4GD-B  - 575usd

So which one should I chose and why?

go with cheapest sapphire. I had the vrm blow on 3, yes 3, gigabyte 7970 so I no longer trust them. They were not over clocked and one was ONLY used for gaming and not even much gaming.

Sapphire is a solid card. From my understanding they are also good with support if needed.
