i have become suspicious of both my gtx 480 gpus as they are only producing about 10,000 PPD each on the 112XX series of work units. is there any way to monitor gpu usage in linux?

`nvidia-settings -q all` allows you to view loads of interesting data about your GPUs. You can even combine this in a script with -t to easily feed the values to RRD graphs and the like.

thanks smoking2000 that will give me plenty to think about for awhile! one last thing though do we still need to use the "forcegpu nvidia_fermi" flag or has the 6.40r1 client eliminated the need for this?
