while i heard rumors about latency problems of the proprietary nvidia 
driver, i did not experience any latency issues. when i did some histograms 
for the multicore signal processing engine of supernova on my nehalem 
workstation, i was measuring a maximum jitter of about 10 microseconds. 
unless you don't want to use the proprietary nvidia driver for political 
reasons, it is fine to run it for low-latency applications ... but testing 
it is probably better than relying on personal opinions ...
