Does FreeBSD 6.0 fully support PCI-Express?

Hi list,

I've been having troubles getting OpenGL applications' performance up to 
par. I have an Nvidia Geforce 6800GT with a PCI-Express interface and I 
use nvidia's closed FreeBSD drivers.

I have been told that FreeBSD (and consequently the nvidia driver) do not 
fully support PCI-Express which makes my card operate at the same speed of 
a plain old PCI bus, which would be a logical explanation for my troubles. 
I have however not been able to find _anything_ on the matter on google 
and I am now wondering how much truth there is to this.

My question is in the subject, I hope someone can clarify this as I it 
will help me decide to get an AGP card instead or perhaps keep trying to 
figure out if I have misconfigured something.

Thanks in advance,
