Watch that laptop doesn't overheat. Laptops are not good miners.

I second this. I've had several high perforamnce laptops and they ALWAYS ran at 80c+ when gaming and that's not under full load. I understand mobile chips are meant to have a higher heat tolerance and the 7-series runs cooler but my my I do hope you don't ruin 2 amazing mobile GPUs.

With cgminer i use -g 2 which is gpu threads, get 600-680 with scrypt, rad 7970. Cpu threads must be irrelevant, surely.

7970m is basically under-clocked desktop 7870
desktop 7870 at 1000/1500 MHz gives about 400kH/s ... https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparison
so 250kH is maybe appropriate, probably not possible to go over 300
in guiminer try to use defaults for 7870 not for 7970
try thread-concurrency 15360 or 16384
maybe also try cgminer instead of reaper to see if there is difference
BTW what is your GPU temperature during mining?
