Based on the specs posted on videocardz the number of cuda cores is a lot less than expected. Therefore, the raw MD5 cracking speed should at ~10.9 BH/s. As comparison, the reference 290x is doing ~11.7 BH/s. For SHA1, it will be around 3852 MH/s and the 290x is at 3720 MH/s.
Do not forget it's mostly the chipset instructions that gives the 980 it's comeback into crypto not the raw hardware power. Therefore, algorithms that can not make use of the instructions will be slower on the 980. For example DEScrypt, it will be around 100 MH/s and 290x is at 130 MH/s.
The TDP is much better, so it's 160W on the 980 and 290W on the 290x and where's less power consumed there's less heat produced.
My (theoretical) conclusion is that the speed is more or less equal to the speed of the 290x. But for sure the NV drivers will be better (and released more often). The TDP is better, the heat should be less. But most important for the hashcracking scene, the multihash performace forthe unsalted algorithms is ways better.
