Topic: R9 280x Vapor-X sapphire or the R9 290x (Read 850 times)
What is your settings for those R9 280X ? Why the Sapphire is better than other brands?
ok but the best choice is a Sapphire
sapphire toxic is so much better that all the other R9 280x.
It's hard to run reference 290x's at full speed unless its like 70F or less. And 280x i think are still a better value per Kh/s last i checked.
Hi Guys,
Currently looking to expand my mining farm and i am not too sure to invest more on the R9 280x or the r9 290x Sapphire. I own 8 r9 280x vapor-x sapphire. 3 Of it hashing at 725Kh and the to other 5 hashing at 680 kh. I won't want to push too much as i under volt it around 1083 VDDC each of it. Not sure why the other 5 can't reach 725kh.
Anyway should i continue getting the r9 280x or go for the r9 290x?
Thanks
