If any of you out there are looking for some sort of benchmark / comparison between the big 2 video card manufacturers, Toms Hardware has posted a review between the AMD FirePro V8800 and the Nvidia Quadro 5000. The article is somewhat short on useful benchmarking data, but it is one of the few "Workstation" class video card benchmarks that I have run across.

Here you go:
Workstation Graphics Car Benchmark

====SPOILER ALERT======
The new Quadros are faster than the FirePros. (Not so) Shocking conclusion: AMD has crappy drivers.
