I'm wondering if it is better to buy a r9 290 or a 2 r9 270s for mining, and then which brand would be the best, respectively.

More about : 290 270s mining

Which currency are you mining? If its litecoin than 2 270s will do better then one 290.

well i would prefer 290 ...at 900 k/hash and more effiecnt if u plan on increasing cards .... go with Gigabyte windforce or Sapphire toxic .. u will find those specific brands are kinda expensive than anothers because they are the best for mining .... another brands heats really up.... be sure u do good air for those by risers and fan pushing air to them

It's been getting more difficult to mine. There's no guarantee that you will even pay off of the cost of hardware and electricity any more. Statistically, it might be best to join a group.

Don't expect any advice you get today to be valid in three months either, but the general trend is that it's getting HARDER to make any profit.

If you want to GAME as well, then avoid Crossfire and get a single card.

As for BRANDS, that's just about quality, though obviously the higher FREQUENCY cards perform better.

One card worth mentioning that's not on your list is the Sapphire R9-280X TOXIC. It can overclock up to about 90MHz above it's factory overclock and is a well made card.

I'm currently mining with a couple R9 280X's and game on them also. I would go with a single MSI R9 290 GAMING http://www.amazon.com/gp/product/B00HPS4AFG for a couple reasons. 1. The R9 290 will be more power efficient while mining, 2. it has more VRAM and scrypt mining loves RAM, and 3. the R9 290 will retain it's value much longer.
