Hi all! Are these the cards that are sold in gpucoin store? Found a sweet local deal on them. If they're not, is it worth picking these for mining? What would be hashrates for them on known algos? thanks in advance.

Code:

Brand Gigabyte
Model Radeon R9 280X
MPN GV-R928XOC-3GD

I have 4xGigabyte GV-R928XOC-3GD-GA. I think it almost the same.
Hashrate for some algo:
Scrypt - ~710kH/s
Scrypt-N - ~360kH/s
x11 - ~2000kH/s
Some settings - core - 1025MHz, memory - 1500Mhz, vddc - 1.075v
Other algos i don't tested

I have the same card and I am getting 748 kh/s stable. Try zuikkis bin from here ( http://www.reddit.com/r/dogemining/comments/1uj4uk/optimized_scrypt_kernel_for_hd7970_r9_280x/ ).I barely reach 720 without it..
1052mhz core, 1500mhz memory

I get lower hashrate than you for scrypt-N though.. about 315kh/s

That's low for a 280X. I haven't used zuuikkis' bin but i'm getting 730KH/s on scrypt (1050/1500, powertune -20 and 1.137 on Trixx) and 360 on scrypt -N (1000/1500, powertune -20, 1.131V).
