i dont understand those digits and numbers, if someone has any of those i mentioned, i would like to hear what they have to say

in case that you have free electricity, which card would be the best, i dont care for noise or heat either

If you have free electricty you can use whatever you get cheap
best cards are rated for low electrict consumption so if ytou are getting free electricty choose cheap and best gpu and start running every second if precious with free electricty.

that is exactly what i plan to do, just need you guys to point me to high consuption and hashrate cards

I heard the 280X Toxic is one of if not the best 280X for mining.

[pagona]

what is khash/s for it?

[evansearle42]

most r9 280x good, the problem is they are out of stock most of the time..

[jorginto]

I have 3 PowerColor Radeon R9 280X TurboDuo OC. Nice and quiet cards, a bit wormer than gigabyte. Running around 710 khash@1,09V. Not the best overclockers, low ASIC reads (60% ish), so to reach 750 khash, You'll need around 1,15V and 1080 MHz core speed. Still the price is very good. If you dont care about electricity costs, powercolor is not a bad chioce. TBH, I would look for Sapphire Dual X (11221-00-20G).

Guys I created a WIKI for the 280x under Mining/Hardware lets put all our thoughts in that thread:

now is hard to find Sapphire Dual X here 

they say that those R9 280X are good at Watt/MH, is there some cheaper card with a similar hashrate, but poor in Watt/MH?



there is good thread about 280X https://bitcointalk.org/index.php?topic=470496.new#new

what about Sapphire R9 270X Toxic, 2GB GDDR5?

[Nthused]

I would get the 3GB Gigabyte R9 280X WindForce 3X OC GV-R928XOC-3GD

I use the same but Gaming Edition and get a stable 730kh/s Stock as a rock

what is difference between Windforce and basic?

MSI Gaming for pure hash. Keep in mind though, the new revisions (38SB, 48SB) etc cannot be undervolted via custom bios at this time in linux. A windows hack exists but doesn't retain settings after reboot and needs to be applied each time.

[delphs]

what is khash/s for it?

My toxic does a steady 750kh/s running at 76C

so you say that MSI Radeon R9 280X GAMING 3 GB is better choice than Gigabyte Radeon R9 280X OC, 3GB?

i am interested in hashrate of those

is that out of box?

The main knock on the Sapphire cards is that the company has poor warranty support.  You have to jump through hoops, pay for shipping, etc. before they will honor it.  I've hear MSI and others are much better.
