Use the --gpu-platform option in cgminer. You need to be running 2 instances of cgminer, one for nvidia devices and one for amd devices.

im running 6950.

using GUIMINER scrypt, latest radeon drivers, installed SDK first.

and I have to create a reaper miner in guiminer and the default settings work for that

cgminer always used my Nvidia gtx even when i selected my device as the cayman GPU

PC seems to slow down a big overall though

I have plenty of ram

thanks this worked: --gpu-platform 1

Pc still slow @ intensity 18 even though all my monitors I use are on the Nvidia. just some quick short hangups

cgminer shows a higher/more steady hashrate @ 398 at stock 6950 8000 thread concurrency

If you are getting hang ups then their might be a bottle neck on your miner system that or the heat of the cards is really high so they slowdown/stop to prevent damage due to overheating.
