By the way - way is the hardware crap? Can you please be more specific? 
AMD claims to have a higher effective double precision throughput than 
nVidia, they also claim not having cut off most of their double 
precision capable facilities like nVidia even on their mass market 
products (but I'm not sure about that since this fact is very often 
hidden by intention). Their software doesn't really matter since I most 
FreeBSD users use the open source driver. Well, I never saw a working 64 
bit capable driver on FreeBSD, that's right.

Please do not understand this as a tricky question, I'm serious, since I 
plan to purchase new hardware for my computer at home (FreeBSD) and even 
for my lab's computer(s).

And by the way, no, I havn't bought 'Evergreen', I have much more 
disappointing HD4830 and not properly working HD4770 and HD4670 ... (not 
GPGPU capable by design).
