guys sorry to bother, i need a little input here. i have checked this one on the litecoin harware mining comparison wiki page:
R9 290, GV-R929D5-4GD-B
and it says it runs at 817-830 khash/s
it's the current best gpu that has reached my country
do you think it is "the" card i need to mine nyans?
thanks!
r9 290 is good to mine any coins, not only nyancoins. We've built up a rig using 11 x R9 290 and everything is working perfectly (mining nyancoins with it atm as nyancoins are the best!)
